It has been tested on various datasets of human populations and proved to be superior to existing methods with analogous aim such as SPA and PCA. We apply GPS analysis to rice datasets and report our findings.

In particular, we compute the class of the stack of transitive vertex algebroids. We define deformations of sheaves of twisted chiral differential operators introduced in \cite{AChM} and use the classification result to describe and classify such

We show that such algebras possess families of modules depending on infinitely many complex parameters, which we ...
