The Composition Tableau and Reconstruction of the Canonical Weierstrass Section for Parabolic Adjoint Action in type
Yasmine Fittouhi, Anthony Joseph
A "Composition map" is constructed, leaning heavily on earlier work [Y. Fittouhi and A. Joseph, Parabolic adjoint action, Weierstrass sections and components of the nilfibre in typ…
The Canonical Component of the nilfibre for Parabolic adjoint action in type
Yasmine Fittouhi, Anthony Joseph
This work is a continuation of [Fittouhi and Joseph, Parabolic adjoint action, Weierstrass Sections and components of the nilfibre in type ]. Let be a parabolic subgroup of…
Parabolic Adjoint Action, Weierstrass Sections and Components of the Nilfibre in Type
Yasmine Fittouhi, Anthony Joseph
This work is a continuation of [Y. Fittouhi and A. Joseph, Weierstrass Sections for Parabolic adjoint action in type ]. Let be an irreducible simple algebraic group and …
Weierstrass sections for parabolic adjoint action in type
Yasmine Fittouhi, Anthony Joseph
The notion of "Weierstrass Section", comes from Weierstrass canonical form for elliptic curves. In celebrated work [B. Kostant, Lie group representations on polynomial rings, Amer.…
Trails, -graphs and Identities in Demazure Modules
Anthony Joseph
The Kashiwara crystal parametrizes a basis for the Verma module of a Kac-Moody algebra. It has a deep combinatorial structure which one seeks to understand. For each se…
Convexity properties of the canonical S-graphs
Anthony Joseph
Let n be a positive integer and c an n-tuple of natural numbers. A convex set in Euclidean n-space given by a family of linear relations in the elements of c and depending on their…
