Non-Commutative Moduli Spaces and T-duality
We review and extend recent work on the application of the noncommutative geometric framework to an interpretation of the moduli space of vacua of certain deformations of N = 4 super Yang-Mills theories. We present a simple worldsheet calculation that reproduces the field theory results and sheds some light on the dynamics of the Dbrane bubbles. Different regions of moduli space are associated ...
متن کاملPath Integrals and Perturbative Expansions for Non-Compact Symmetric Spaces
We show how to construct path integrals for quantum mechanical systems where the space of configurations is a general non-compact symmetric space. Associated with this path integral is a perturbation theory which respects the global structure of the system. This perturbation expansion is evaluated for a simple example and leads to a new exactly soluble model. This work is a step towards the con...
متن کاملModuli spaces for Bondal quivers
Given a sufficiently nice collection of sheaves on an algebraic variety V , Bondal explained how to build a quiver Q along with an ideal of relations in the path algebra of Q such that the derived category of representations of Q subject to these relations is equivalent to the derived category of coherent sheaves on V . We consider the case in which these sheaves are all locally free and study ...

متن کاملModuli Spaces And
Let M g,l be the moduli space of stable algebraic curves of genus g with l marked points. With the operations which relate the different moduli spaces identifying marked points, the family (M g,l) g,l is a modular operad of projective smooth Deligne-Mumford stacks, M. In this paper we prove that the modular operad of singular chains C * (M; Q) is formal; so it is weakly equivalent to the modula...
