We introduce a reduced form of a Birman᎐Murakami᎐Wenzl algebra associated to the braid group of Coxeter type B and investigate its semisimplicity, Bratteli diagram, and Markov trace. Applications in knot theory and physics are outlined.

✦ Synopsis
In this paper we consider the Birman Wenzl algebras over an arbitrary field and prove that they are cellular in the sense of Graham and Lehrer. Furthermore, we determine for which parameters the Birman Wenzl algebras are quasi-hereditary. So the general theory of cellular algebras and quasi-hereditary algebras applies to Birman Wenzl algebras. As a consequence, we can determine all irreducible representations of the Birman Wenzl algebras by linear algebra methods. We prove also that the new Hecke algebras induced from Birman Wenzl algebras are Frobenius over a field (but not always cellular).

Let R be a commutative algebra over a field k. We prove two related results on the simplicity of Lie algebras acting as derivations of R. If D is both a Lie subalgebra and R-submodule of Der k R such that R is D-simple and either char k = 2 or D is not cyclic as an R-module or D R = R, then we show
