Crossing Barriers

Hitting and stopping time problems in finance and insurance · University of Bath, 14–15 January 2010

Problems involving hitting and stopping times are ubiquitous across financial and insurance mathematics, and as both fields have advanced and drawn in more sophisticated models, the need to advance the corresponding mathematical techniques has grown with them.

In mathematical finance, hitting- and stopping-time problems arise classically in the study of American and barrier options, but also in robust hedging, real option theory and the modelling of credit default events. In insurance, the major application is to ruin theory — often complicated by perturbations of the surplus process corresponding to dividend strategies, such as path refraction and path reflection. The aim of the workshop was to bring together academics from the finance and insurance communities to share recent advances in the techniques connected to hitting and stopping problems.

The workshop was supported by the European Science Foundation, the AXA Research Fund, the ESF AMAMEF programme, Prob-L@b and the Bath Institute for Complex Systems (BICS). Scientific organisers: Alexander Cox, Andreas E. Kyprianou and Kees van Schaik.

Bursaries

A limited number of bursaries were available to research students and to participants from the former Soviet Union, Africa, or countries covered by the LMS “Scheme 5”. Bursaries went towards the cost of accommodation, reducing the registration fee.

Organisers

Organised by Alexander Cox, Andreas E. Kyprianou and Kees van Schaik, at the Department of Mathematical Sciences, University of Bath.
