An Analytical Approach to the equivariant index and Witten genus on spin manifolds
Juan Jose Villarreal
This work is divide in two cases. In the first case, we consider a spin manifold as the set of fixed points of an -action on a spin manifold , and in the second case…

Nilmanifolds and their associated non local fields
Juan Jose Villarreal
For six dimensional nilmanifolds we build a module of an affine Kac Moody vertex algebras. Then, we associate some logarithmic fields for the module and…

The Computation of the Möbius Function of a Möbius Category
Emil Daniel Schwab, Juan Villarreal
The paper presents some results for reducing the computation of the Möbius functon of a Möbius category that arises from a combinatorial inverse semigroup to that of locally finite…
