Fórmula de integración en espacios con la propiedad de continuidad del subdiferencial

Salas Videla, David Sebastián January 2013 (has links)
Ingeniero Civil Matemático / En esta memoria se extiende el resultado de integración de Correa y Hantoute presentado en \cite{Correa1}, que dice que si un espacio de Banach $X$ tiene la propiedad de Radon-Nykod\'ym (RNP), entonces para todo par de funciones $f,g:X\to\Rex$ con $f$ epi-pointed y semicontinua inferior, y tal que $\partial f\subseteq \partial g$, se cumple que existe una constante $c\in\R$ tal que \[ \cco f = \overline. \] Se introduce la noción de funciones integrables, que tienen las condiciones necesarias y suficientes para que la fórmula de integración anterior se cumpla, independiente de la RNP. Además, se definen las funciones cuasi-integrables, que son aquellas funciones $f$ epi-pointed que sólo necesitan para ser integrables que exista un denso $D$ del interior del dominio de $f^*$ donde se satisfaga que \[ \clss = \partial f^*(x^*),\quad\forall x^*\in D. \] Se dan caracterizaciones de la ecuación anterior y luego se define la familia de espacios de Banach donde para toda función $f$ epi-pointed, su conjugada satisface dicha ecuación en un denso del interior de su dominio: Los espacios cuyo dual tiene la propiedad de continuidad del subdiferencial débil ($w$-SCP). Se muestra que esta es la familia de espacios de Banach más grande donde toda función cuasi-integrable es integrable. Se termina la memoria dando varias caracterizaciones de los espacios cuyo dual tiene la $w$-SCP y se plantean algunas conjeturas sobre la estructura de los mismos.

In chapter 1 we prove that the traditional Rademacher functions can be replaced by the generalized ones in the definitions of type and cotype in complex Banach spaces. It is also shown that there are standard type Kahane inequalities for the generalized Rademacher functions. Next we provide new applications of the notions of type and cotype to the theory of multilinear mappings and homogeneous polynomials in Banach spaces. In chapter 2 we show how the notion of type can be used to construct LebesgueBochner spaces-valued multilinear mappings and homogeneous polynomials. With the help of the notion of cotype, in chapter 3 we prove several results about absolutely summing multilinear mappings and homogeneous polynomials. / Doutorado / Doutor em Matemática
