Multi-valued mappings and Lefschetz fixed point theorems
Mathematical Proceedings of the Cambridge Philosophical Society, 1970 By a multi-valued map from a space X to a space Y we mean a map which assigns to each point x in X a non-empty subset F(x) of Y. When X = Y, a point x in X is a fized point for F if x is in F(x).

Lefschetz Fixed Point Theorem and Intersection Homology
, 1984 This article is a summary of the essential ingredients in [3]. We will consider a placid self-map with isolated fixed points on a subanalytic pseudomanifold and show that the trace of the induced homomorphism on intersection homology may be interpreted as a sum of certain linking numbers at the fixed points.

On the Lefschetz fixed point theorem for Random multivalued mappinngs
LIBERTAS MATHEMATICA (new series), 2013 The aim of this paper is to prove the Lefschetz xed point theorem for random multivalued compact absorbing contractions on abssolute neighbourhood multiretracts (ANMR) spaces.

Digital Lefschetz numbers and related fixed point theorems
Revista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas, 2022Motivated by the \(4\)-contractibility of \(SC_4^{2,4}\), we may consider the so-called strong \(k\)-homotopy in a digital setting, where \(SC_4^{2,4}\) means a simple closed \(4\)-curve with \(4\) elements in \(\mathbb{Z}^2\). Indeed, based on the literature, several types of homologies from the viewpoint of digital topology such as digital homology ...

The Lefschetz Fixed Point Theorem for Involutions
1968The purpose of this note is to show that the Lefschetz fixed point theorem holds for involutions on locally compact spaces. The Alexander-Spanier-Wallace cohomology with compact supports will be used. Let X be a locally compact space. The Lefschetz number Λ f of a map f: X → X is defined by $${A_{f}} = \sum\limits_{i} {{{\left( { - 1} \right)}^{i}}}

Journal of Fixed Point Theory and Applications, 2014
The authors consider the so-called admissible continuous set-valued maps with compact attractors and satisfying some compactness conditions stated in terms of measures of noncompactness and prove a general version of the Lefschetz-type fixed point theorem along with some corollaries.
