Profinite algebras and affine boundedness

, 2016
We prove a characterization of profinite algebras, i.e., topological algebras that are isomorphic to a projective limit of finite discrete algebras. In general profiniteness concerns both the topological and algebraic characteristics of a topological ...

Operadic formulation of topological vertex algebras and Gerstenhaber or Batalin-Vilkovisky algebras

, 1993
We give the operadic formulation of (weak, strong) topological vertex algebras, which are variants of topological vertex operator algebras studied recently by Lian and Zuckerman. As an application, we obtain a conceptual and geometric construction of the

Excitations in strict 2-group higher gauge models of topological phases

Journal of High Energy Physics, 2020
We consider an exactly solvable model for topological phases in (3+1) d whose input data is a strict 2-group. This model, which has a higher gauge theory interpretation, provides a lattice Hamiltonian realisation of the Yetter homotopy 2-type topological

Singular dimensions of the N=2 superconformal algebras. I [PDF]

, 1998
Verma modules of superconfomal algebras can have singular vector spaces with dimensions greater than 1. Following a method developed for the Virasoro algebra by Kent, we introduce the concept of adapted orderings on superconformal algebras.

Gelfand theorem implies Stone representation theorem of Boolean rings

International Journal of Mathematics and Mathematical Sciences, 1995
Stone Theorem about representing a Boolean algebra in terms of open-closed subsets of a topological space is a consequence of the Gelfand Theorem about representing a B∗- algebra as the algebra of continuous functions on a compact Hausdorff space.

Topological tensor product of bimodules, complete Hopf Algebroids and convolution algebras [PDF]

, 2018
Given a finitely generated and projective Lie-Rinehart algebra, we show that there is a continuous homomorphism of complete commutative Hopf algebroids between the completion of the finite dual of its universal enveloping Hopf algebroid and the ...

Two Dimensional String Theory and the Topological Torus

, 1992
We analyze topological string theory on a two dimensional torus, focusing on symmetries in the matter sector. Even before coupling to gravity, the topological torus has an infinite number of point-like physical observables, which give rise via the BRST ...

Twisted Topological Graph Algebras Are Twisted Groupoid C*-algebras

, 2017
The second author showed how Katsura's construction of the C*-algebra of a topological graph E may be twisted by a Hermitian line bundle L over the edge space E.

TOPOLOGICAL MATTER, MIRROR SYMMETRY AND NON-CRITICAL (SUPER)STRINGS [PDF]

, 1995
We study the realization of the (super) conformal topological symmetry in two-dimensional field theories. The mirror automorphism of the topological algebra is represented as a reflection in the space of fields.
