Abstract:

In this talk I will survey results illustrating

the large scale effect in quatities of mathematical,

physical or biological interest when some

of the key parameters controling the underlying

problem are discontinuous. Our understanding

of these effects, as well as the properties of the

solutions, benefits from studying the associated stochastic

process and in particular the properties of its

local time. In particular, the connections between

interface conditions and the notion of `natural local

time' will be explored. This talk is based in joint work

with T Appuhamillage, V Bokil, E Waymire and B Wood.
