Double Centralizer Properties Dominant Dimension and ...

Double ,centralizer, properties play a central role in many parts of algebraic Lie theory. Soergel’s double ,centralizer theorem, relates the principal block of the Bernstein Gelfand Gelfand category O of a semisimple complex Lie algebra with the coinvariant algebra i.e., the cohomology algebra of the corresponding flagŽ manifold . Schur.

An important fact in the theory of central simple algebras is the double centralizer theorem, which says: if k is a field, A is a k -algebra, V is a faithful semisimple A -algebra, then, C (C (A)) =, A,, where C (A) is, the, centralizer of A in E n d k (V)., Taking the centralizer is an inclusion-reversing operation.

Direct proof that the centralizer of \$GL(V)\$ acting on \$V ...

Based on the lectures I have outlined so far, I think this will be one of the few key results. The standard proof is to show that the, centralizer of k [ S n] is spanned by G L (V),, and then apply the, double, centralizer theorem.

(UNFINISHED NOTES ON) MORDELL’S CONJECTURE AFTER …

By the double ,centralizer theorem, (recalled above) Z E(Z) = End(A) Q l, therefore it su ces to show that, for any 2End(V lA)Gal K and c2Z, we have c= c 2End(V lA): In other words, let c2End(V lA) be an element that commutes with all x2End(A) Q l, then we need to show that ccommutes with as well. Now the clever part of the argument: consider the ...

SCHUR'S DOUBLE CENTRALIZER THEOREM FOR TRIANGULAR …

tiplication. In this setting (an equivalent form of) Schur's, double centralizer theorem, states thatS», and £/(gl(K)) are mutual centralizers in End^ V%m. This result was generalized to super vector spaces by [BR], and both these sit-uations were translated into a Hopf algebraic setting and thus given a natural, proof, by the second author [Fi].
