RT Journal Article T1 New criteria for the existence of non-trivial fixed points in cones A1 Cabada Fernández, Alberto A1 Cid Araújo, José Ángel A1 Infante, Gennaro K1 Krasnosel’skii fixed point theorem K1 Positive solutions K1 Conical shells K1 Multiplicity AB We give new criteria for the existence of nontrivial fixed points on cones assuming some monotonicity of the operator on a suitable conical shell. Moreover, we give an application to the existence of multiple solutions for a nonlocal boundary value problem that models the displacement of a beam subject to some feedback controllers PB Springer YR 2013 FD 2013-05-13 LK https://hdl.handle.net/10347/45949 UL https://hdl.handle.net/10347/45949 LA eng NO Cabada, A., Cid, J.Á. & Infante, G.
