Funciones no-estándar y teoría de distribuciones

Any sequence of real functions (fn) induces a function f = gen (fn) in the non-standard reals R* by taking the ultraproduct πn and lt; R,fn and gt;/F (F a non-principal ultrafilter). This papeP studies the algebra and the caculus of the functions so obtained. Derivatives and integrals are defined as...
