Nodal solutions for nonlinear nonhomogeneous Robin problemsPapageorgiou, Nikolaos S. (Avtor) Rǎdulescu, Vicenţiu (Avtor) Repovš, Dušan (Avtor) nodal solutionsindefinite potentialnonhomogeneous differential operatornonlinear regularity theorytruncation and cut-off techniquesWe consider a nonlinear Robin problem driven by a nonhomogeneous differential operator plus an indefinite potential. The reaction term is a Carathéodory function satisfying certain conditions only near zero. Using suitable truncation, comparison and cut-off techniques, we show that the problem has a sequence of nodal solutions converging to zero in the ▫$C^1(\overline{\Omega})$▫-norm.20182019-08-29 10:43:55Članek v reviji109291UDK: 517.956ISSN pri članku: 1120-6330DOI: 10.4171/RLM/831COBISS_ID: 18514777OceCobissID: 15928665sl
