Exponential decay phenomenon of the principal eigenvalue of an elliptic operator with a large drift term of gradient type
Shuichi Jimbo, Masato Kimura, Hirofumi Notsu
We study an asymptotic behaviour of the principal eigenvalue for an elliptic operator with large advection which is given by a gradient of a potential function. It is shown that th…

Quantitative uniqueness for second order elliptic operators with strongly singular coefficients
Ching-Lung Lin, Gen Nakamura, Jenn-Nan Wang
In this paper we study the local behavior of a solution to second order elliptic operators with sharp singular coefficients in lower order terms. One of the main results is the bou…
