Topological degree for supersymmetric chiral models

Physical Review D, 1985
For the case of an N-field supersymmetric chiral model we discuss the relationship between the Witten index, the topological degree, the winding number, and the degree of polynomials. Using results of classical analysis we can then place strong constraints on the Witten index of supersymmetric chiral models.

Topological Degree: An Introduction

2013
In this chapter, we construct the Brouwer topological degree and extended it for compact perturbations of the identity in a Banach space, namely, the Leray–Schauder degree. Some topological consequences are presented. Moreover, we give applications to some boundary value problems.

Topological Degree and Complementarity

2000
Certainly, when we speak about the application of topological methods to Complementarity Theory, the first subject, which must be considered, is the applications of topological degree to the study of complementarity problems.

Nonresonance and Topological Degree

2016
In this chapter we show how the topological degree can be used to find periodic solutions of our second order differential equation. Many different situations will be considered, leading to the existence and also multiplicity of periodic solutions.

Degree 3 Networks Topological Routing [PDF]

, 2009
Topological routing is a table free alternative to traditional routing methods. It is specially well suited for organized network interconnection schemes. Topological routing algorithms correspond to the type O(1), constant complexity, being very attractive for large scale networks.

Generalized Topological Degree and Bifurcation

1986
The main task of this paper is to present a generalized degree theory for continuous maps f: Ū→ℝn, where U ⊂ ℝm,m ≥ n is a bounded open subset such that f(x) ≠ 0 for all x ∈ ∂U - the boundary of U - (as usual U stands for the closure of U).

Characterizations of \((L,M)\)-fuzzy topology degrees

2018
Summary: In this paper, characterizations of the degree to which a mapping \(\mathcal{T}\,:\,L^X\to M\) is an \((L,M)\)-fuzzy topology are studied in detail. What is more, the degree to which an \(L\)-subset is an \(L\)-open set with respect to \(\mathcal{T}\) is introduced.

The Topological Degree of A-Proper Maps

Canadian Journal of Mathematics, 1971
Recently several fixed-point theorems have been proved for new classes of non-compact maps between Banach spaces. First, Petryshyn [15] generalized the concept of compact and quasi-compact maps when he introduced the P-compact maps and proved a fixed-point theorem for this class of maps.
