Dilation theory for rank two graph algebras. [PDF]

open access: yes, 2010
An analysis is given of $*$-representations of rank 2 single vertex graphs. We develop dilation theory for the non-selfadjoint algebras $\A_\theta$ and $\A_u$ which are associated with the commutation relation permutation $\theta$ of a 2-graph and, more ...

Resolution of Fuzzy Relational Inequalities with Boolean Semi-Tensor Product Composition

open access: yesMathematics, 2021
Resolution of fuzzy relational inequalities (FRIs) plays a significant role in decision-making, image compression and fuzzy control. This paper studies the resolution of a kind of FRIs with Boolean semi-tensor product composition.

Tensor Products and Bimorphisms [PDF]

open access: yesCanadian Mathematical Bulletin, 1976
The binary tensor product, for modules over a commutative ring, has two different aspects: its connection with universal bilinear maps and its adjointness to the internal hom-functor. Furthermore, in the special situation of finite-dimensional vector spaces, the tensor product can also be described in terms of dual spaces and the internal hom-functor ...

The 2-Deligne Tensor Product [PDF]

open access: yes, 2021
We prove that the 2-Deligne tensor product of two compact semisimple 2-categories exists. Further, under suitable hypotheses, we explain how to describe the $Hom$-categories, connected components, and simple objects of a 2-Deligne tensor product. Finally,

On the convergence of the combination technique [PDF]

open access: yes, 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

Frame-indifference of cross products, rotations, and the permutation tensor

open access: yesTheoretical and Applied Mechanics Letters, 2020
: Under improper transformations, the traditional transformation laws for cross products, the permutation tensor, and rotations are incorrect. For a cross product, using a counter-example the left-hand rule is proved wrong.

Tensor product of correspondence functors [PDF]

open access: yes, 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 ...

The Tensor Product of Polynomials [PDF]

open access: yesExperimental Mathematics, 1999
Using Grobner basis algorithms in MAGMA we find necessary and sufficient conditions for a polynomial of degree 6 over any field to bethe tensor product of two polynomials, one of degree 3 and one of degree 2.

Varying Coefficient Tensor Models for Brain Imaging [PDF]

open access: yes, 2005
We revisit a multidimensional varying-coefficient model (VCM), by allowing regressor coefficients to vary smoothly in more than one dimension, thereby extending the VCM of Hastie and Tibshirani.
