Graded Lie Algebras and Intersection Cohomology
Let (G, ι) be a pair consisting of a reductive connected algebraic group over C and a homomorphism of algebraic groups ι : C∗ −→ G. The centralizer G of ι(C∗) in G acts naturally (with finitely many orbits) on the n-eigenspace LnG of Ad(ι(C∗)) on the Lie algebra LG of G. (Here n ∈ Z − {0}.) If O is a Gorbit on LnG and L is a G-equivariant irreducible local system on O then the intersection coho...
متن کاملResidue in Intersection Homology for Quasihomogeneous Singularities
In [13] we define a residue of a closed form ω ∈ Ω(M \K) as the class of the Leray [9] residue form res ω = [Resω] ∈ H(K\Σ) ≃ Hn(K). All coefficients of homology and cohomology are in C. The following question arises: can one integrate the residue form over cycles intersecting singularity. The question comes from partial differential equations; [14]. It turns out, that certain integrals have a ...
متن کاملSoft intersection Lie algebras
In 1999, Molodtsov introduced the concept of soft set theory as a general mathematical tool for dealing with uncertainty and vagueness, and many researchers have created some models to solve problems in decision making and medical diagnosis. In this paper, we introduce the concept of soft Lie subalgebras (resp. soft Lie ideals) and state some of their fundamental properties. We also introduce t...
متن کاملCohomology and Deformations in Graded Lie Algebras
Introduction. In an address to the Society in 1962, one of the authors gave an outline of the similarities between the deformations of complex-analytic structures on compact manifolds on one hand, and the deformations of associative algebras on the other. The first theory had been stimulated in 1957 by a paper [7] by NijenhuisFrölicher and extensively developed in a series of papers by KodairaS...
متن کاملGraded Lie Algebras and Dynamical Systems
We consider a class of infinite-dimensional Lie algebras which is associated to dynamical systems with invariant measures. There are two constructions of the algebras – one based on the associative cross product algebra which considered as Lie algebra and then extended with nontrivial scalar twococycle; the second description is the specification of the construction of the graded Lie algebras w...
