On Algebraic Integrability of Gelfand-zeitlin Fields
We generalize a result of Kostant and Wallach concerning the algebraic integrability of the Gelfand-Zeitlin vector fields to the full set of strongly regular elements in gl(n, C). We use decomposition classes to stratify the strongly regular set by subvarieties XD. We construct an étale cover ĝD of XD and show that XD and ĝD are smooth and irreducible. We then use Poisson geometry to lift the G...

We construct and investigate a new large family of simple modules over U q (gl n).
متن کاملTopological mass in seven dimensions and dualities in four dimensions
The massive topologically and self dual theories en seven dimensions are considered. The local duality between these theories is established and the dimensional reduction lead to the different dualities for massive antisymmetric fields in four dimensions. The topological Chern Simons terms have played an important role in several physical models. For instance, they appear in the eleven dimensio...
