The operator rings of topological symmetric orbifolds and their large N limit

Journal of High Energy Physics
We compute the structure constants of topological symmetric orbifold theories up to third order in the large N expansion. The leading order structure constants are dominated by topological metric contractions.

Open/Closed String Topology and Moduli Space Actions via Open/Closed Hochschild Actions

Symmetry, Integrability and Geometry: Methods and Applications, 2010
In this paper we extend our correlation functions to the open/closed case. This gives rise to actions of an open/closed version of the Sullivan PROP as well as an action of the relevant moduli space. There are several unexpected structures and conditions

Prolongations of G-structures related to Weil bundles and some applications

Extracta Mathematicae, 2022
Let M be a smooth manifold of dimension m ≥ 1 and P be a G-structure on M , where G is a Lie subgroup of linear group GL(m). In [8], it has been defined the prolongations of G-structures related to tangent functor of higher order and some properties ...

Notes on Number Theory

Mathematics
This paper presents a set of survey-style notes linking core themes of pure algebra with central topics in algebraic and analytic number theory. We begin with finite extensions of Q and describe algebraic number fields through their realization as finite-

Poisson Manifolds, Lie Algebroids, Modular Classes: a Survey

Symmetry, Integrability and Geometry: Methods and Applications, 2008
After a brief summary of the main properties of Poisson manifolds and Lie algebroids in general, we survey recent work on the modular classes of Poisson and twisted Poisson manifolds, of Lie algebroids with a Poisson or twisted Poisson structure, and of ...

Graded Frobenius Algebras

The Quarterly Journal of Mathematics
ABSTRACT We construct a symmetric monoidal category, specifically a PROP, that encodes 2D-TQFTs with a grading. This defines a graded Frobenius algebra as algebras over this PROP. We also give a description of graded Frobenius algebras in terms of maps and relations.
