In this talk we settle this question: given two metrizable spaces X and Y and a subfamily of C(X,Y), what are necessary and sufficient conditions for there to exist compatible metrics d on X and q on Y so that the family becomes Lipschitzian...
In this talk we settle this question: given two metrizable spaces X and Y and a subfamily of C(X,Y), what are necessary and sufficient conditions for there to exist compatible metrics d on X and q on Y so that the family becomes Lipschitzian with respect to these...
I hope to describe how Galois fields can be used to construct: first Camina p-groups P (with [P, x] = P′ for every element x ∈ P − P′) [1]; then semidirect products of an extraspecial normal subgroup by a cyclic group [2]; and finally (in response to a question asked...
El teorema de la curva de Jordan establece que una curva cerrada simple separa el plano en dos componentes conexas, una acotada y la otra no. En la década de los 70's, Azriel Rosenfeld publicó en una serie de artículos una versión discreta del teorema de la...
The Bergman space Ap(Ω), 1 ≤ p < ∞, on a domain Ω ⊂ 𝐂 is by definition the closed subspace of Lp(Ω) consisting of holomorphic functions; here, the Lp-space is defined via the real area measure of Ω. The Bergman projection PΩ is the orthogonal projection from L2(Ω)...
