20.500.12556/RUL-116656 Nonlinear singular problems with indefinite potential term We 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. nonhomogeneous differential operator indefinite potential singular term concave and convex nonlinearities truncation comparison principles nonlinear regularity nonlinear maximum principle true false true Angleški jezik Angleški jezik Članek v reviji 2020-06-01 08:59:14 2020-06-01 08:59:17 2022-08-28 03:51:32 0000-00-00 00:00:00 2019 0 0 Str. 2237-2262 iss. 4 Vol. 9 Dec. 2019 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 517.956.2 1664-2368 10.1007/s13324-019-00333-7 18663001 18662745 RAZ_Papageorgiou_Nikolaos_2019.pdf RAZ_Papageorgiou_Nikolaos_2019.pdf 1 0010C0F1D76FFCBB6A064344C2769FA4 114f86a298b53b0802bbb9057cf52e5b73ae19e9e8c41f2a5eddc9c39fdb1845 fb4af8b2-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130302 Pedagoška fakulteta Fakulteta za matematiko in fiziko 0 0 0
