Sobre la existencia y el cálculo de ceros de funciones regulares [Article]
(Real Academia de Ciencias Exactas, Físicas y Naturales, 1988)
For a map / of class two a sufficient condition is obtained to secure the existence of a zero of f in the simplex 5 if a piecewise Hnear aproximation 9 of f has a cero in s. Application: for a smooth map F: D ⊆ Cn → Cn a ...
A special type of triangulations in numerical nonlinear analysis [Article]
(Universitat de Barcelona, 1990)
To calculate the zeros of a map f : D ⊆ Rn → Rn we consider the class of triangulations of Rn so that a certain point belongs to a simplex of fixed diameter and dimension. In this paper two types of this new class of ...
Weakly coercive mappings sharing a value [Article]
(Academy of Sciences of Czech Republic, Mathematical Institute, 2011)
Some sufficient conditions are provided that guarantee that the difference of a compact mapping and a proper mapping defined between any two Banach spaces over K has at least one zero. When conditions are strengthened, ...
On complete convergence for arrays of rowwise independent random elements [Article]
(Korean Mathematical Society, 2007)
A complete convergence theorem for arrays of rowwise independent random variables was proved by Sung, Volodin, and Hu. In this paper, we extend this theorem to the Banach space without any geometric assumptions on the ...
Fourier uniqueness sets and the Klein-Gordon equation [Presentation]
Building on ideas from H. Hedenmalm, H., Montes-Rodríguez, A., Heisenberg uniquenes pairs and the Klein-Gordon equation. Ann. of Math. 173 (2011), 1507-1527, we introduce (local) Fourier uniqueness sets for spaces of ...
