A characterization of Dynkin elements
We give a characterization of the Dynkin elements of a simple Lie algebra. Namely, we prove that one-half of a Dynkin element is the unique point of minimal length in its N -region. In type An this translates into a statement about the regions determined by the canonical left Kazhdan-Lusztig cells.
متن کاملAnnihilators of nilpotent elements
For an element x of a ring R, let A (x), Ar(x), and A(x) denote, respectively, the left, right and two-sided annihilator of x in R. For a set X , we denote cardX by |X|; and say that a subset Y of X is large in X if |Y | = |X|. We prove that if x is any nilpotent element and I is any infinite ideal of R, then A(x) ∩ I is large in I , and in particular |A (x)| = |Ar(x)| = |A(x)| = |R|. The last ...
متن کاملNilpotent Elements in Skew Polynomial Rings
Letbe a ring with an endomorphism and an -derivationAntoine studied the structure of the set of nilpotent elements in Armendariz rings and introduced nil-Armendariz rings. In this paper we introduce and investigate the notion of nil--compatible rings. The class of nil--compatible rings are extended through various ring extensions and many classes of nil--compatible rings are constructed. We al...
متن کاملNilpotent Orbits and Commutative Elements
Let W be a simply-laced Coxeter group with generating set S, and let Wc denote the subset consisting of those elements whose reduced expressions have no substrings of the form sts for any non-commuting s; t 2 S. We give a root system characterization of Wc, and in the case where W corresponds to a nite Weyl group, show that Wc is a union of Spaltenstein-Springer-Steinberg cells. The latter is v...
متن کاملNilpotent Elements of Residuated Lattices
Ward and Dilworth 1 introduced the concept of residuated lattices as generalization of ideal lattices of rings. The residuated lattice plays the role of semantics for a multiple-valued logic called residuated logic. Residuated logic is a generalization of intuitionistic logic. Therefore it is weaker than classical logic. Important examples of residuated lattices related to logic are Boolean alg...
