Tensor product dual frames

Journal of Inequalities and Applications, 2019
To construct dual frames with good structure for a given frame is a fundamental problem in the theory of frames. The tensor product duals of tensor product frames can provide a rank-one decomposition of bounded antilinear operators between two Hilbert ...

Tensor Product of Evolution Algebras [PDF]

Mediterranean Journal of Mathematics, 2022
AbstractThe starting point of this work is the fact that the class of evolution algebras over a fixed field is closed under tensor product. We prove that, under certain conditions, the tensor product is an evolution algebra if and only if every factor is an evolution algebra.

Product States of Infinite Tensor Product of JC-algebras

Axioms
The objective of our study is to generalize the results on product states of the tensor product of two JC-algebras to infinite tensor product JC-algebras.

Precise Tensor Product Smoothing via Spectral Splines

Stats
Tensor product smoothers are frequently used to include interaction effects in multiple nonparametric regression models. Current implementations of tensor product smoothers either require using approximate penalties, such as those typically used in ...

Tensor product of A∞-categories [PDF]

Journal of Pure and Applied Algebra
In this paper we define the tensor product of two A∞-categories and two A∞- functors. This tensor product makes the category of A∞-categories symmetric monoidal (up to homotopy), and the category A∞Catu/≈ a closed symmetric monoidal category. Moreover, we define the derived tensor product making Ho(A∞Cat), the homotopy category of the A∞-categories, a ...

On the convergence of the combination technique [PDF]

, 2013
Sparse tensor product spaces provide an efficient tool todiscretize higher dimensional operator equations. The direct Galerkin method in such ansatz spaces may employ hierarchical bases, interpolets, wavelets or multilevel frames. Besides, an alternative

Tensor product of correspondence functors [PDF]

, 2019
As part of the study of correspondence functors, the present paper investigates their tensor product and proves some of its main properties. In particular, the correspondence functor associated to a finite lattice has the structure of a commutative ...
