A remark on surjectivity of quasibounded P-compact maps
, 1976 Usando la teoria spettrale per operatori non lineari, recentemente introdotta da M. Furi ed A. Vignoli, si dà un teorema di suriettività per operatori P-compatti e quasi limitati. Come corollario si ottiene un teorema dovuto a W. V.

Surjective Function Theorems [PDF]
, 1999 Given the unit sphere Sn, we prove the following theorem and several extensions: For any continuous function f : Sn - Sn, if f has no fixed point in Sn, then f must be surjective.

Nonlinear cellular automata are extensively used in simulations, image processing, cryptography, and so on. The determination of their fundamental properties, injectivity and surjectivity, related to information loss during the evolution, is necessary in

Surjectivity of Gaussian maps for curves on Enriques surfaces
, 2007 Making suitable generalizations of known results we prove some general facts about Gaussian maps. These facts are then used, in the second part of the article, to give a set of conditions that insure the surjectivity of Gaussian maps for curves on ...
