Supercharacters, symmetric functions in noncommuting variables, and related Hopf algebras

Marcelo Aguiar, Carlos Andre, Carolina Benedetti +25

We identify two seemingly disparate structures: supercharacters, a useful way of doing Fourier analysis on the group of unipotent uppertriangular matrices with coefficients in a fi…

Algebras associated with Pseudo Reflection Groups: A Generalization of Brauer Algebras

Zhi Chen

We present a way to associate an algebra $B_{G} (Υ)$ with every pseudo reflection group $G$ . When $G$ is a Coxeter group of simply-laced type we show $B_{G} (Υ)$ is isomorphic to the…
