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 $\lambda (s)$ as $s\to +\infty$ for the following elliptic equation \begin{align*} -Δφ(x)-2s\mathbf{v}\cdot\nablaφ(x)+c(x)φ(x)…
