Non-convergence of the principal eigenvalue of elliptic operators for large advection

Xueli Bai, Zhi-An Wang, Xin Xu +2

This paper investigates the limit of the principal eigenvalue $I^» (s)$ as $s \to + \infty$ for the following elliptic equation \begin{align*} -ÎÏ(x)-2s\mathbf{v}\cdot\nablaÏ(x)+c(x)…
