▫$(p,2)$▫-equations asymmetric at both zero and infinityPapageorgiou, Nikolaos S.

The reaction term is ▫$(p-1)$▫-linear, but exhibits asymmetric behavior at ▫$\pm \infty$▫ and at ▫$0^\pm$▫. Using variational tools, together with truncation and comparison techniques and Morse theory, we prove two multiplicity theorems, one of them providing sign information for all the solutions (positive, negative, nodal).20182019-08-26 14:03:55Članek v reviji109201UDK: 517.956.2ISSN pri članku: 2191-9496DOI: 10.1515/anona-2017-0195COBISS_ID: 18174297OceCobissID: 16253785sl
