Symplectic Geometry of character varieties and Lattice Gauge Theory I
T. R. Ramadas
Given a finite connected graph , the space of lattice gauge-fields on , modulo gauge transformations, is a Lagrangian submanifold -- with mild singularities -- of the…

Rational and global forms of certain Chiral Conformal Field Theories; Vertex Algebras I
T. R. Ramadas
We present explicit global constructions - avoiding power series - of certain chiral CFTs, including current algebras on the projective line. We outline an approach to vertex algeb…

Parabolic bundles and representations of the fundamental group
Tomas L. Gomez, T. R. Ramadas
Let X be as smooth complex projective variety with Neron-Severi group isomorphic to Z, and D an irreducible divisor with normal crossing singularities. Assume r is equal to 2 or 3.…
