Sobre las soluciones periódicas del problema de dirichlet para ecuaciones de tipo parabólico
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1985)
It is shown that for a Dirichlet's periodic problema studied by Lazer: L(u) = g(x,t,u)+f1(x,t)+s
Taking categories seriously
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1986)
The theory of categories originated [1] with the need to guide complicated calculations involving passage to the limit in the study of the qualitative leap from spaces to homotopical/homological objects.

Separably real closed local rings
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1985)
It is well known that several types of "variable reals" arising in topos theory (Dedekind reals, Cauchy reals, smooth reals, etc.) are not real closed, in the sense that a polynomial (with "variable real" coefficients) ...
Best approximation in vector valued function spaces
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1985)
Let T be the unit circle, and m be the normalized Lebesgue measure on T. If H is a separable Hilbert space, we let L∞T,H) be the space of essentially bounded functions on T with values in H. Continuous functions with values ...
Synthetic reasoning in differential geometry
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1986)
All manifolds acquire in the context of synthetic differential geometry (SDG) a binary relation, the "neighbour" relation ~, which is symmetric and reflexive, but not transitive.
Natural numbers in illative combinatory logic
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1985)
In this paper we attempt to develop natural numbers using the second order predicate calculus and the three axioms also used to obtain the set theory of [3].

Lazer-solimini equation with state-dependent delay: an alternative demonstration
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 2013)
In this paper, an alternative proof of results in [6] is given; there, the existence of T-periodic solutions of a family of Lazer-Solimini equations with state-dependent delay is studied. The tools used in the proof are a ...
