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)…

Exact blow-up profiles for the parabolic-elliptic Keller-Segel system in dimensions $N \geq 3$

Xueli Bai, Maolin Zhou

In this paper, we obtain the exact blow-up profiles of solutions of the Keller-Segel-Patlak system in the space with dimensions $N \geq 3$ , which solves an open problem proposed by P…
