Cycles from resonant amplification of demographic stochasticity
Alan McKane
(University of Manchester)
Abstract:
In this talk I will discuss how the formalism of master equations
may be applied to study the stochastic dynamics of a number of
problems in population biology and biochemistry. When they contain a
large number of constituents, the behaviour of these systems may be
analysed using an expansion in the system size. To leading order the
deterministic analogues of the models can be compared to the
equations which are normally written down on phenomenological
grounds. At next to leading order a simplified stochastic
description is obtained. Attention will focus on systems for which
the deterministic description fails to predict cycles, but where
large cycles are found at next-to-leading order through a resonant
amplification of demographic fluctuations. The generality and
applicability of these results will be discussed.

The wave function behavior of the open topological string
Amir-Kian Kashani-Poor
(University of Amsterdam)
Abstract:
Suppose we could calculate the string partition function to all genera using worldsheet methods. What could we learn from this expression about a potentially underlying (non-perturbative) target space description of the theory? We address this question in the context of the open topological A-model.
