The Calculation of the Topological Degree by Quadrature
SIAM Journal on Numerical Analysis, 1975The topological degree of a function on $R^n $, a useful tool in applied mathematics, is computed by applying Gauss–Legendre quadrature to Kronecker’s integral definition. An error analysis is developed from the Sarma–Eberlein measure of goodness.

The Topological Degree of A-Proper Maps
Canadian Journal of Mathematics, 1971Recently 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.

In this chapter we develop the theory of topological degree. We first deal with the case of a finite dimensional space, by constructing the Brouwer degree. We then extend such a construction to the infinite dimensional setting, introducing the Leray–Schauder degree.

Topological Degree in Infinite Dimensions
1985In this basic chapter we shall study some basic problems concerning equations of the form f (x) = y, where f is a continuous map from a subset Ω ⊂ ℝ n into ℝ n and y is a given point in ℝ n . First of all we want to know whether such an equation has at least one solution x ∈Ω.

Degrees of recursively enumerable topological spaces
Journal of Symbolic Logic, 1983In [5], Metakides and Nerode introduced the study of recursively enumerable (r.e.) substructures of a recursively presented structure. The main line of study presented in [5] is to examine the effective content of certain algebraic structures. In [6], Metakides and Nerode studied the lattice of r.e.

Nonresonance and Topological Degree
2016In 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.

On Turing degrees of points in computable topology
Mathematical Logic Quarterly, 2008AbstractThis paper continues our study of computable point‐free topological spaces and the metamathematical points in them. For us, a point is the intersection of a sequence of basic open sets with compact and nested closures. We call such a sequence a sharp filter.

Topological Degree and Complementarity
2000Certainly, 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.

A New Topology with Odd Degree for Multiprocessor Systems
Journal of Parallel and Distributed Computing, 1996A new topology for interconnection networks has been proposed. The underlying network graph hasN= 4nnodes (n? 2) and isalmostregular with maximum degree 5 and diameter ? ?3/4 log2N? + 1. Algorithms for point-to-point routing and single node broadcast have also been developed.
