Nonlinear singular problems with indefinite potential termPapageorgiou, Nikolaos S. (Avtor) Rǎdulescu, Vicenţiu (Avtor) Repovš, Dušan (Avtor) nonhomogeneous differential operatorindefinite potentialsingular termconcave and convex nonlinearitiestruncationcomparison principlesnonlinear regularitynonlinear maximum principleWe consider a nonlinear Dirichlet problem driven by a nonhomogeneous differential operator plus an indefinite potential. In the reaction we have the competing effects of a singular term and of concave and convex nonlinearities. In this paper the concave term will be parametric. We prove a bifurcation-type theorem describing the changes in the set of positive solutions as the positive parameter ▫$\lambda$▫ varies.20192020-06-01 08:59:14Članek v reviji116656UDK: 517.956.2ISSN pri članku: 1664-2368DOI: 10.1007/s13324-019-00333-7COBISS_ID: 18663001OceCobissID: 18662745sl
