Merging of degree and index theory [PDF]
Fixed Point Theory and Applications, 2006 The topological approaches to find solutions of a coincidence equation can roughly be divided into degree and index theories. We describe how these methods can be combined. We are led to a concept of an extended degree theory for function triples which

Periodic solution of a bioeconomic fishery model by coincidence degree theory
Electronic Journal of Qualitative Theory of Differential Equations, 2023 In this article we use coincidence degree theory to study the existence of a positive periodic solutions to the following bioeconomic model in fishery dynamics \begin{equation*}\label{eq1.3} \begin{cases} \frac{dn}{dt} = n \left(r(t) \left(1-\frac{n ...

Periodic Third-Order Problems with a Parameter
Axioms, 2021 This work concerns with the solvability of third-order periodic fully problems with a weighted parameter, where the nonlinearity must verify only a local monotone condition and no periodic, coercivity or super or sublinearity restrictions are assumed, as

Structure of the Fixed Point of Condensing Set-Valued Maps [PDF]
Mathematics Interdisciplinary Research, 2020 In this paper, we present structure of the fixed point set results for condensing set-valued map. Also, we prove a generalization of the Krasnosel'skii-Perov connectedness principle to the case of condensing set-valued maps.
