Topological Degree Computation

2001
In this chapter we address the problem of computing topological degree of Lipschitz functions. From the knowledge of the topological degree one may ascertain whether there exists a zero of a function inside the domain, a knowledge that is practically and theoretically worthwile.

The Topological Degree

2016
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

1985
In 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.
