Tópicos fundamentais da estrutura eletrônica de materiais cristalinos, são investigados de forma generalizada mediante o Cálculo Fracionário. São calculadas as bandas de energia, as funções de Bloch e as funções de Wannier, ...

Let T∈ L(H), and let T=U|T|= |T*| U be the polar decomposition of T . Then, for every λ∈[0,1], the λ-Aluthge transform is defined by D λ (T )= |T| l U|T| 1-λ . We show that several properties which are known for the usual ...

In this paper we study a family of singular integral operators that generalizes the higher order Gaussian Riesz Transforms and find the right weight w to make them continuous from L1(wdγ) into L1,∞(dγ), being dγ(x) = e-x2dx. ...

This paper develops the structure of consumer's rational choice problem inside the decision theory framework taking the consumption set as a Riesz space under different information conditions. It shows traditional concepts ...

Este libro contiene elementos importantes tanto del cálculo fraccional como del q-fraccional. Está diseñado para profesionales en Matemáticas, Física y ciencias de Ingenierías que deseen tener una primera aproximación a ...
