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.

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.

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.
Mit freundlichen Grüßen

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

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

``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
