Abstract Continuation methods of Leray-Schauder type represent an important tool in the theory of differential and integral equations. Roughly speaking,…

AbstractIn this paper we prove some continuation theorems for mappings of Caristi type. Our results generalize Caristi’s fixed point theorem…

Abstract Let \(G\) be a bounded open subset of a Banach space \(X\) with \(0\in G\) and let \(f\) be…

Abstract We propose a generalization of the topological transversality theorem of Granas [1] (see also [2]). We show the implication…

AbstractThe author shows that one may derive the property of homotopy invariance for the fixed point index (for compact maps…
