Hidden time scales and stochastic dynamics
Applied problems viewed through mathematical models often pose
new questions that require a combination of mathematical perspectives. This
talk will cover a few applications in stochastic dynamics where dramatic
noise-sensitive effects result from hidden features in the models. These
examples illustrate what might be missed by using any one "classical"
approach to understand the phenomena. New combined approaches reveal the
hidden features behind the noise-sensitivity and suggest reduced problems
which are more manageable than the original model for understanding the
dynamics. Models for epidemics, chatter, and waves will be discussed,
with some illustration about generalizations to other applications.
Refreshments will be served at 2:45 p.m. (MATX 1115, Math Lounge).
