  • Concentration phenomena in nonlinear eigenvalue problems with variable exponents and sign-changing potential
    Mihǎilescu, Mihai ; Rǎdulescu, Vicenţiu, 1958-
    In this paper we establish the concentration of the spectrum in an unbounded interval for a class of eigenvalue problems involving variable growth conditions and a sign-changing potential. We also ... study the optimization problem for the particular eigenvalue given by the infimum of the associated Rayleigh quotient when the variable potential lies in a bounded, closed, and convex subset of a certain variable exponent Lebesgue space.
