Asymptotic analysis of the Narrow Escape Problem in general shaped domain with several absorbing necks
Xiaofei Li, Shengqi Lin
This paper considers the two-dimensional narrow escape problem in a domain which is composed of a relatively big head and several thin necks. The narrow escape problem is to comput…
