Positive solutions for singular double phase problemsPapageorgiou, Nikolaos S. (Avtor) Repovš, Dušan (Avtor) Vetro, Calogero (Avtor) double phase problemsingular termNehari manifoldpositive solutionsdiscontinuous weightWe study the existence of positive solutions for a class of double phase Dirichlet equations which have the combined effects of a singular term and of a parametric superlinear term. The differential operator of the equation is the sum of a ▫$p$▫-Laplacian and of a weighted ▫$q$▫-Laplacian ▫$(q<p)$▫ with discontinuous weight. Using the Nehari method, we show that for all small values of the parameter ▫$\lambda > 0$▫, the equation has at least two positive solutions.20212021-07-19 08:48:51Neznano128542sl
