DESCRIPTION
Diffusion processes arise in modelling a variety of
random dynamic phenomena in the physical, biological,
engineering and social sciences. They are also connected to the
subject of partial differential equations via potential
theory. Rather than describing the general theory without a
context,
this course will describe some of
the properties and potential applications of diffusions through
the concrete example of reflecting Brownian motions
and applications to queueing networks. (Queueing networks are
of current relevance for modelling communication networks and manufacturing
systems.)
Some aspects of the auxiliary topics of Markov processes,
weak convergence in path space, and applications
of stochastic calculus will also be discussed.
PREREQUISITES
A first graduate course in probability is highly
recommended (e.g., Math 280).
Those who do not have a background in Brownian motion,
continuous martingales or stochastic calculus may wish
to attend the last three weeks of
Math 280B and at least the first part of Math 280C, when
these subjects will be discussed there.
FIRST MEETING
The first meeting will be in HSS 2152 on Monday, April 1 at 11 a.m.
Future meetings may be held at a different time. This will be
discussed at the first meeting.
Students interested in the course are asked to
indicate their interest to Professor Williams by sending email to
williams@math.ucsd.edu. Questions may also be directed to this
address.
