model"*

**

/Abstract: The PASEP (partially asymmetric exclusion process) is a toy 
model in the physics of dynamical systems. It is defined with a Markov 
chain on sets of particles moving on a strip. Explicit expressions for 
the stationary probabilities of the most general model(with 5 
parameters) has been given by physicists, using the (orthogonal) 
Askey-Wilson polynomials. The resolution is based on a certain "matrix 
Ansatz" related to a quadratic algebra defined by generators and the 
unique relation DE = qED + E + D. Many works have been done by 
combinatorists interpreting these stationary probabilities with certain 
families of weighted "tableaux". Deep combinatorics appears, related to 
the symmetric group and moment of orthogonal polynomials (in particular 
some q-Laguere polynomials).A bijection between these tableaux and 
permutations play a key role and can be constructed from a combinatorial 
representation of the above quadratic "PASEP algebra". This 
representation is inspired from operators coming from computer science 
in the study of dynamical data structures and has the same flavor as the 
construction of the classical Robinson-Schented correspondence from a 
representation of the most simple Heisenberg-Weyl algebra/

/(defined by DU = UD + Id). /
