DESCRIPTION:Lewis Topley\, University of Birmingham\nIn a recent work Lose
 v constructed a version of the orbit method for semisimple Lie algebras: t
 his is a map from the set of coajoint orbits to the primitive spectrum of 
 the enveloping algebra.\nFor classical Lie algebras the map is known to b
 e injective and Losev conjectured that the image should consist of primiti
 ve ideals obtained from one dimensional representations of W-algebras via 
 Skryabin's equivalence.\nIn this talk I will explain his construction\, a
 nd my proof of this conjecture. One of the key steps is the use of Dirac
  reduction to obtain new presentations of the semiclassical limits of fin
 ite W-algebras.\n\nzoom Passcode: 231451
