---------- Forwarded message ---------- From: Walter Schachermayer <wschach(a)fam.tuwien.ac.at> ---------- Forwarded message ---------- Date: Wed, 27 Oct 2004 11:17:18 +0100 From: Andrew Cairns <A.Cairns(a)ma.hw.ac.uk> To: Andrewc(a)ma.hw.ac.uk Subject: ANNOUNCEMENT: conference/workshop Dear Colleagues, I have appended below a short announcment of a workshop on quantitative finance and insurance that will be held in Edinburgh in 2005. Please forward this announcement to any colleagues that you think might be interested. For further details please see the draft workshop website at http://www.ma.hw.ac.uk/~andrewc/workshop/ To give me an idea of numbers, persons hoping to attend and/or give a talk should e-mail me at A.Cairns(a)ma.hw.ac.uk Yours sincerely, Andrew Cairns Heriot-Watt University, Edinburgh Workshop on the Interface between Quantitative Finance and Insurance Dates: 4-8 April, 2005 A satellite workshop of the Quantitative Finance programme of the Isaac Newton Institute, January - June 2005. Organised jointly by: Heriot-Watt University, Edinburgh The International Centre for Mathematical Sciences, Edinburgh The Isaac Newton Institute, Cambridge Organising Committee: Andrew Cairns (Heriot-Watt University) Claudia Klueppelberg (Technical University of Munich), Susan Pitts, Chris Rogers (University of Cambridge) General Summary This workshop aims to discuss leading-edge research on the interface between insurance, pensions and quantitative finance. It is intended that the meeting will concentrate on two closely linked themes. First, all insurance companies and pension plans are subject to a degree of financial and economic risk as well as their traditional insurance risks. Considerable research in the international actuarial community is ongoing which attempts to model and manage these risks. Much of this research is building upon existing knowledge in financial mathematics. Equally, though, the specific problems being encountered are throwing back new challenges for financial mathematicians. This introduces us to the second theme. Namely the issue of securitisation of insurance risks. This presents many new challenges which require a combination of financial mathematics, mathematical economics and good contract design. Workshop Themes A: Stochastic asset models for life insurance and pensions B: Fair value, solvency testing and capital adequacy C: Long-term risks: pricing and risk assessment D: Dependence modelling, extreme-value theory, Levy processes and their application in insurance problems E: Optimal stochastic control and optimal hedging problems in insurance F: Issues relating to specific contracts and securitisation of insurance risks

Timetable Tuesdays and Thursdays, 16:30-18:00, TU FH, Turm A, 6. Stock, Seminarraum 107. Th, 28.10.2004 Philippe Clement (TU Delft) R-Boundedness and Operator-valued Multipliers In this lecture we shall introduce the notion of R-bounded family of operators in a Banach space. Recently many new results in the theory of operator-valued multipliers (of Marcinkiewicz, Mihlin or Schur type) have been obtained by using this new notion of boundedness. Connections with the problem of Lp-maximal regularity for abstract differential equations in Banach spaces will also be considered. http://www.fam.tuwien.ac.at/events/

---------- Forwarded message ---------- From: Walter Schachermayer <wschach(a)fam.tuwien.ac.at> ---------- Forwarded message ---------- Date: Mon, 11 Oct 2004 14:29:16 +0200 From: Nicole Gruber <oek(a)eos.tuwien.ac.at> Subject: Ökonometrisches Seminar Sehr geehrte InteressentInnen, am Montag, 18. Oktober 2004 (13:15 bis 14:45 Uhr) hält Herr Dr. Thomas Ribarits einen Vortrag mit dem Titel: "Neue Parametrisierungen für lineare Zeitreihenmodelle: der stationäre und der kointegrierte Fall" Ort: Seminarraum 105A (Argentinierstraße 8, 1. Stock). Abstract: Im Vortrag betrachten wir die Maximum Likelihood Schätzung von linearen dynamischen Systemen in Zustandsraumdarstellung. Zur Schätzung muß vorab die Modellklasse geeignet parametrisiert werden. Wir stellen neue Parametrisierungen vor: 'separable least squares data driven local coordinates' (slsDDLC). SlsDDLC basiert einerseits auf der Grundidee von DDLC, einer Parametrisierung, die in (McKelvey et al., 2004) eingeführt wurde. Andererseits fußt slsDDLC auf der Anwendung der 'separable least squares Methodologie', d.h. slsDDLC wird zur Optimierung einer geeignet konzentrierten Likelihoodfunktion verwendet. Dies bedeutet natürlich auch eine verminderte Zahl von zu schätzenden Parametern im nichtlinearen Likelihood-Optimierungsproblem. Die Anwendung der Parametrisierungen auf die Maximum Likelihood Schätzung von stationären Zeitreihenmodellen wird illustriert. Simulationsstudien zeigen, daß die Verwendung von slsDDLC deutliche numerische Vorteile im Vergleich zu traditionellen Parametrisierungen, aber auch zu DDLC, aufweist. Schließlich wird die Anwendung auf die Schätzung kointegrierter Zeitreihenmodelle besprochen. Die in (Johansen, 1995) behandelte VAR (vektor-autoregressive) Modellierung von kointegrierten Prozessen wird verallgemeinert und slsDDLC wird für die Schätzung des neu eingeführten Zustandsraum-Fehlerkorrekturmodells verwendet. Schlagworte: Multivariate Zeitreihenanalyse, Zustandsraummodelle, Parametrisierungen, stationäre Prozesse, Kointegration.

---------- Forwarded message ---------- From: Walter Schachermayer <wschach(a)fam.tuwien.ac.at> ---------- Forwarded message ---------- Date: Fri, 8 Oct 2004 13:40:19 -0700 From: Edwin Perkins <perkins(a)math.ubc.ca> To: wschach(a)fam.tuwien.ac.at Subject: 2005 Summer School in Probability June 6-30, U. British Columbia As part of our PIMS Collaborative Research Group in Probability and Statistical Physics we will again be running two advanced graduate courses at UBC in the summer of 2005. The lectures in 2005 will take place from June 6 to June 30 and be given by Yuval Peres, U Cal. Berkeley, and Gordon Slade, UBC. The course descriptions are below. We plan these to be official courses at UBC and so graduate students at universities in W. Canada can receive credit for them through the Western Deans Agreement. There will be total of 30 hours of lectures in each course. Support for these courses comes from the Pacific Institute for the Mathematical Sciences and the Department of Mathematics at UBC. Those interested in attending these courses (graduate students, pdf's , faculty members) are encouraged to sign up asap at our website http://www.pims.math.ca/science/2005/ssprob/ as there will be limited space in the lecture rooms. There will be some financial support available for a limited number of graduate students and postdoctoral fellows who would like to attend. This will basically cover the cost of a dorm room for the duration of the course. Applications for support should consist of a brief letter of application, a cv of the prospective student/pdf and a letter from the applicant's supervisor all of which may be emailed to ssprob(a)pims.math.ca. Plain text is preferred. The deadline for applications for financial support is Dec. 31. It would help us greatly with planning if you could let us know of your interest before Oct. 31 at the above address. If you have queries about the courses please check our website at http://www.pims.math.ca/science/2005/ssprob/ or send questions to Gordon Slade at slade(a)math.ubc.ca. Sincerely, David Brydges and Ed Perkins. For summer 2005 the courses will be given by Yuval Peres and Gordon Slade, and will run from 6 June 2005 - 30 June 2005 ----------------------------------------------------------------- Yuval Peres (Math 610D) Title: Mixing for Markov Chains and Spin Systems Instructor: Yuval Peres, UC Berkeley Given an aperiodic irreducible Markov chain on a finite state space, the rate at which it approaches its stationary distribution is intensively studied by mathematical physicists, computer scientists and probabilists. The key insight is that as we consider running the chain for longer times, we should also be considering chains on larger spaces. Two celebrated families of chains that still pose mysteries are random walks on the symmetric group (card shuffles) and "Glauber dynamics" of spin systems; canonical examples for the latter are the Ising model and graph colorings. Planned topics: * Markov chains and electrical networks: a brief primer. * Probabilistic methods: coupling and strong uniform times. * Mixing via spectral gap and isoperimetric inequalities. * Expanders via random constructions and zigzag products. * The Ising model and the random cluster model. * The Ising model on trees, and its interpretations in mathematical genetics and noisy computation. * Glauber dynamics for spin systems. * Correlation inequalities and their implications for mixing. * Cover times and lamplighter groups. * Exact sampling via coupling from the past. Three areas, teeming with unsolved problems, that we will explore: * Connections between mixing in time and space for spin systems * Comparison of updates at random locations and systematic scans * The cutoff phenomenon for distance to stationarity Gordon Slade (Math 609D) ``The lace expansion and its applications" Abstract: Several superficially simple mathematical models, such as the self-avoiding walk and percolation, are paradigms for the study of critical phenomena in statistical mechanics. It remains a major challenge for mathematical physics and probability theory to obtain a mathematically rigorous understanding of the scaling theory of these models at criticality. The lace expansion has become a powerful tool for the analysis of the critical scaling of a number of models above their upper critical dimensions, including the self-avoiding walk, lattice trees, lattice animals, oriented and non-oriented percolation, and the contact process. Results include proof of existence of critical exponents, with mean-field values, and construction of the scaling limit. For lattice trees and critical percolation, the scaling limit is described in terms of super-Brownian motion. The lectures will provide an introduction to the lace expansion and several of its applications. No previous exposure to the lace expansion will be assumed, and necessary background will be provided. Lecture notes for the course are available at http://www.math.ubc.ca/~slade/sf_v1.ps.gz
