Cari saluti,

Titolo: 

Small representations for reduced enveloping algebras

Abstract: 

Although the ordinary representation theory of Lie algebras is extremely well developed, progress has been much slower in the modular case. A breakthrough was made twenty years ago when Premet proved a long-standing conjecture bounding the dimensions of modules. His techniques led to the discovery of finite W-algebras, and the latter theory has recently culminated in another milestone, showing that the bound mentioned before is best possible. I shall review the development of this theory and discuss some very recent results of mine regarding the structure theory of certain modular finite W-algebras
