Frames and Bases in Tensor Product of Hilbert Spaces
Frame bases Tensor product Frame operator Dual frame Hilbert space
2012/4/17
In this article we develop a theory for frames in tensor product of Hilbert spaces. We show that like bases if Y_1, Y_2, \cdot \cdot \cdot, Y_n are frames for H_1,H_2, \cdot \cdot \cdot, H_n, respecti...
On the Approximation of Contractive Semigroups of Operators in Discretizable Hilbert Spaces
Contractive Semigroups Evolution Equations Discretizable Hilbert Space
2011/2/25
The Computation of discrete Contractive semigroups becomes necessary when we deal with several types of evolution equations in Discretiz-able Hilbert spaces, in this work we study some properties of t...
