Global Theory

  • Hansjörg Kielhöfer
Part of the Applied Mathematical Sciences book series (AMS, volume 156)


Comparable to the importance of the Implicit Function Theorem for the local analysis is the degree of a mapping for any global analysis. Although the theory was originally invented and defined in topology we present an analytical theory developed later. For finite-dimensional continuous mappings it is the Brouwer degree; its extension to infinite dimensions is the Leray–Schauder degree.
