The first eigenvalue of pLaplacian systems with nonlinear boundary conditionsThe first eigenvalue of pLaplacian systems with nonlinear boundary conditions Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-292005enWe study the properties of the positive principal eigenvalue and the corresponding eigenspaces of two quasilinear elliptic systems under nonlinear boundary conditions. We prove that this eigenvalue is simple, unique up to positive eigenfunctions for both systems, and isolated for one of themΔημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/Boundary Value Problems307-322.
