Existence and perturbation of principal eigenvalues for a periodic-parabolic problem
We give a necessary and sufficient condition for the existence of a positive principal eigenvalue for a periodic-parabolic problem with indefinite weight function. The condition was originally established by Beltramo and Hess [extit{frenchspacing Comm. Part. Diff. Eq.}, extbf{9} (1984), 919--941] in...
