The Raikov Convolution Measure Algebra
What follows is propaganda for the study of a particular commutative Banach algebra, A one not inappropriate to a conference which emphasises automatic continuity. In fact A is that subalgebra of the measure algebra, .i\J(T), of all regular bounded Borel measures on the circle under the total variation norm and convolution multiplication, which is characterised by the automatic continuity of me...
متن کاملalgebra and wreath product convolution
We present a group theoretic construction of the Virasoro algebra in the framework of wreath products. This can be regarded as a counterpart of a geometric construction of Lehn in the theory of Hilbert schemes of points on a surface. Introduction It is by now well known that a direct sum ⊕ n≥0R(Sn) of the Grothendieck rings of symmetric groups Sn can be identified with the Fock space of the Hei...

متن کاملAn Algebra Containing the Two-Sided Convolution Operators
We present an intrinsically defined algebra of operators containing the right and left invariant Calderón-Zygmund operators on a stratified group. The operators in our algebra are pseudolocal and bounded on Lp (1 < p <∞). This algebra provides an example of an algebra of singular integrals that falls outside of the classical Calderón-Zygmund theory.
متن کاملPursuing the Double Affine Grassmannian Ii: Convolution
This is the second paper of a series (started by [3]) which describes a conjectural analog of the affine Grassmannian for affine Kac-Moody groups (also known as the double affine Grassmannian). The current paper is dedicated to describing a conjectural analog of the convolution diagram for the double affine Grassmannian. In the case when G = SL(n) our conjectures can be derived from [12].
