A Weighted Bossel-Daners Transfer Principle and a Pure-Power Robin Faber-Krahn Inequality

Tan Duc Do, Nguyen Ngoc Trong, Nguyen Ngoc Huy Truong

We prove a weighted Bossel-Daners transfer principle for the first Robin eigenvalue of the $p$-Laplacian under $w=m^{1/p^{\prime }}$, where $p^{\prime }=p/(p-1)$. The argument combines double-densit…
