Topological degree in the generalized Gause prey-predator model
We consider a generalized Gause prey-predator model with T -periodic continuous coefficients. In the case where the Poincaré map P over time T is well defined, the result of the paper can be explained as follows: we locate a subset U of R2 such that the topological degree d(I −P,U) equals to +1. The novelty of the paper is that the later is done under only continuity and (some) monotonicity ass...
متن کاملGeneralized Topological Degree and Semilinear Equations
The topological degree is a fundamental concept in algebraic topology and in analysis, and the number of its applications to nonlinear differential equations has increased at an impressive rate during the whole second half of this century. The concept can be rooted in the fundamental work of Kronecker [8] on systems of smooth real functions f0, f1, . . . , fn of n real variables such that 0 is ...

متن کاملOn ev-degree and ve-degree topological indices
Recently two new degree concepts have been defined in graph theory: ev-degree and ve-degree. Also the evdegree and ve-degree Zagreb and Randić indices have been defined very recently as parallel of the classical definitions of Zagreb and Randić indices. It was shown that ev-degree and ve-degree topological indices can be used as possible tools in QSPR researches . In this paper we d...
متن کاملA topological degree for operators of generalized (S+)$(S_{+})$ type
As an extension of the Leray-Schauder degree, we introduce a topological degree theory for a class of demicontinuous operators of generalized (S+) type in real reflexive Banach spaces, based on the recent Berkovits degree. Using the degree theory, we show that the Borsuk theorem holds true for this class. Moreover, we study the Dirichlet boundary value problem involving the p-Laplacian by way o...
