Axiomática para el grado muitivaluado
(Real Academia de Ciencias Exactas, Físicas y Naturales, 1988)
In this paper we develop an axiomatic theory for the multivalued degree that preserves the basic properties of the classical degree. We apply it to obtain fixed point theroems and existence of solution fix) = p. We give a ...
