Description
I will give a gentle introduction to some recent work on the
effects of long-range temporal correlations in stochastic
particle systems, focusing particularly on fluctuations
about the typical behaviour. Specifically, in the first part
of the talk, I will discuss how long-range memory dependence
can modify the large deviation principle describing the
probability of rare currents and lead, for example, to
superdiffusive behaviour. In the second part of the talk, I
will describe a more interdisciplinary project incorporating
the psychological "peak-end" heuristic for human memory into
a simple discrete choice model from economics. Along the
way, I will attempt to indicate connections between
different approaches, other possible applications
(especially to biology), and open questions.
