Limiting behavior of principal eigenvalues for a class of mixed boundary value problems as the measure of the support domain goes to zero

J. Lopez-Gomez, A. Sahuquillo

In this paper we characterize the limiting behavior of the principal eigenvalue, $\s_1[-\D,\b,Ø]$, of the boundary value problem \eqref{1.1} as the Lebesgue measure of the underlyi…
