The Birman-Murakami-Wenzl algebra (BMW algebra) of type Dn is shown to be semisimple and free of rank (2^n+1)n!!-(2^(n-1)+1)n! over a specified commutative ring R, where n!! is the product of the first n odd integers. We also show it is a cellular algebra over suitable ring extensions of R. The Brauer algebra of type Dn is the image af an R-equivariant homomorphism and is also semisimple and free of the same rank, but over the polynomial ring Z with delta and its inverse adjoined. A rewrite…

Brauer algebras of type B
For each n=1, we define an algebra having many properties that one might expect to hold for a Brauer algebra of type B_n. It is defined by means of a presentation by generators and relations. We show

The Birman-Murakami-Wenzl algebras (BMW algebras) of type En for n = 6; 7; 8 are shown to be semisimple and free over the integral domain $ {{{\mathbb{Z}\left[ {{\delta^{\pm 1}},{l^{\pm 1}},m}
Algebras associated with Pseudo Reflection Groups: A Generalization of Brauer Algebras
We present a way to associate an algebra $B_G (\Upsilon) $ with every pseudo reflection group $G$. When $G$ is a Coxeter group of simply-laced type we show $B_G (\Upsilon)$ is isomorphic to the
Birman-Murakami-Wenzl algebras for general Coxeter groups
We introduce a BMW type algebra for every Coxeter group. These new algebras are introduced as deformations of the Brauer type algebras introduced by the author, they have the corresponding Hecke


Brauer algebras of simply laced type
The diagram algebra introduced by Brauer that describes the centralizer algebra of the n-fold tensor product of the natural representation of an orthogonal Lie group has a presentation by generators
BMW algebras of simply laced type
A generalization of the Kauffman tangle algebra is given for Coxeter type Dn. The tangles involve a pole of order 2. The algebra is shown to be isomorphic to the Birman–Murakami–Wenzl algebra of the
Cellular algebras
AbstractA class of associative algebras (“cellular”) is defined by means of multiplicative properties of a basis. They are shown to have cell representations whose structure depends on certain
Braids, link polynomials and a new algebra
A class function on the braid group is derived from the Kauffman link invariant. This function is used to construct representations of the braid groups depending on 2 parameters. The decomposition of
Let W be a Coxeter group with Coxeter graph Γ. Let H be the associated Hecke algebra. We define a certain ideal I in H and study the quotient algebra H̄ = H/I. We show that when Γ is one of the
On the Quasi-Heredity of Birman–Wenzl Algebras☆
Abstract 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
Homological representations of the Hecke algebra
In this paper a topological construction of representations of theAn(1)-series of Hecke algebras, associated with 2-row Young diagrams will be given. This construction gives the representations in
Hecke algebras of finite type are cellular
Let $\mathcal{H}$ be the one-parameter Hecke algebra associated to a finite Weyl group W, defined over a ground ring in which “bad” primes for W are invertible. Using deep properties of the
