WebParabolic subgroups. Subgroups between a Borel subgroup B and the ambient group G are called parabolic subgroups.Parabolic subgroups P are also characterized, among algebraic subgroups, by the condition that G/P is a complete variety.Working over algebraically closed fields, the Borel subgroups turn out to be the minimal parabolic … WebThe Borel fixed point Theorem and some applications Applications G=B is proper Let B be a Borel subgroup of maximal possible dimension. Find a representation V such that the stabilizer of the high weight vector above is exactly B. Repeat the previous argument on V=Span C(v) and use a bit of induction to obtain the Lie-Kolchin Theorem, i.e. for a

If Pcontains a Borel subgroup B, then we have a surjective morphism G/B→ G/Pthus G/P is proper since G/Bis. Conversely, if G/Pis proper, then any Borel subgroup Bhas a fixed point gP in G/Pthus Bg⊂ gPand g−1Bg⊂ P.

WebThe invertible ones among them form a subgroup of the general linear group, whose conjugate subgroups are those defined as the stabilizer of some (other) complete flag. These subgroups are Borel subgroups. The group of invertible lower triangular matrices is such a subgroup, since it is the stabilizer of the standard flag associated to the ... WebFeb 9, 2024 · The notion of a Borel subgroup can be generalized. Let G G be a complex semi-simple Lie group.
