On I null lie algebras

Gromov introduced translation algebras (over the real or complex fields) in the early 1990’s as certain algebras of infinite matrices, whose entries are indexed by a given

Abstract: We investigate ergodic properties of Markov semigroups in von Neumann algebras with the help of the notion of constrictor, which expresses the idea of close- ness of

In this paper we describe the Cuntz semigroup of continuous fields of C ∗ - algebras over one dimensional spaces whose fibers have stable rank one and trivial K 1 for each

When dealing with compact Lie groups in this context, one quickly realizes that the effect of the BZ/p-homotopy functors on their classifying spaces depends sometimes on properties

While the preceding papers mostly considered abstract properties of algebras of quotients, our main objective is to compute Q m (L) for some Lie algebras L. Specifically, we

One can consider a Jacobi manifold as a generalized phase-space and the Lie algebra of infinitesimal automorphisms as the algebra of symmetries of this phase-space.. Then the

These algebras naturally appear as a residual gauge symmetry in the theory of relativistic membranes [3], which exhibits an intriguing connection with the quantum mechanics of
