Discretising geometry and preserving topology I: A discrete exterior calculus
Vivien de Beauce, Siddhartha Sen
A discretisation scheme that preserves topological features of a physical problem is extended so that differential geometric structures can be approximated in a consistent way thus…
Homology in Abelian Lattice Models
Mark Rakowski, Siddhartha Sen
We study abelian lattice gauge theory defined on a simplicial complex with arbitrary topology. The use of dual objects allows one to reformulate the theory in terms of new dynamica…
Algebraic Aspects of Abelian Sandpile Models
D. Dhar, P. Ruelle, S. Sen +1
The abelian sandpile models feature a finite abelian group G generated by the operators corresponding to particle addition at various sites. We study the canonical decomposition of…
Comments on Witten Invariants of 3-Manifolds for SU(2) and
S. Kalyana Rama, Siddhartha Sen
The values of the Witten invariants, , of the lens space for SU(2) at level are obtained for arbitrary . A duality relation for when and are int…
