Title: On positive solutions to multi-phase problems
Abstract: In this talk, we discuss positive solutions to double-phase and multi-phase problems, where each phase is associated with a weight function. First, we investigate the existence and multiplicity of positive solutions to double-phase problems under conditions imposed on the weight functions, using a Krasnoselskii-type fixed-point theorem. Then we show how analogous results can be obtained for multi-phase problems.
