An algebra containing the two-sided convolution operators [PDF]
We present an intrinsically defined algebra of operators containing the right and left invariant Calderon–Zygmund operators on a stratified group. The operators in our algebra are pseudolocal and bounded on L p ( 1 p ∞ ) .

On the product formula and convolution associated with the index Whittaker transform [PDF]
We deduce a product formula for the Whittaker function W κ , μ whose kernel does not depend on the second parameter. Making use of this formula, we define the positivity-preserving convolution operator associated with the index Whittaker transform, which

Lie groupoid deformations and convolution algebras
We define a morphism from the deformation complex of a Lie groupoid to the Hochschild complex of its convolution algebra, and show that it maps the class of a geometric deformation to the algebraic class of the induced deformation in Hochschild cohomology.

A Note on Function Spaces with Fractional Fourier Transforms in Wiener-type Spaces
The purpose of this paper is to introduce and study a function space A_(α,w)^(B,Y) (R^d ) to be a linear space of functions h∈L_w^1 (R^d ) whose fractional Fourier transforms F_α h belong to the Wiener-type space W(B,Y)(R^d ), where w is a Beurling ...

Convolution measure algebras with involution [PDF]
Let S S be a commutative, locally compact semigroup and A A an L L -subalgebra of M ( S ) M(S) . We obtain conditions on A A to ensure that S S is an inverse semigroup, a group, or an idempotent semigroup. We assume an

Convolution equation and operators on the euclidean motion group
Let $G = \mathbb{R}^2\rtimes SO(2)$ be the Euclidean motion group, let g be the Lie algebra of G and let U(g) be the universal enveloping algebra of g.

Weighted Convolution for Quaternion Linear Canonical Cosine Transform and Its Application
Convolution plays a pivotal role in the domains of signal processing and optics. This paper primarily focuses on studying the weighted convolution for quaternion linear canonical cosine transform (QLCcT) and its application in multiplicative filter ...

Dendriform structures for restriction-deletion and restriction-contraction matroid Hopf algebras [PDF]
We endow the set of isomorphism classes of matroids with a new Hopf algebra structure, in which the coproduct is implemented via the combinatorial operations of restriction and deletion.

Convolution Theorems for Quaternion Fourier Transform: Properties and Applications
General convolution theorems for two-dimensional quaternion Fourier transforms (QFTs) are presented. It is shown that these theorems are valid not only for real-valued functions but also for quaternion-valued functions. We describe some useful properties
