Factorial Schur functions via the six vertex model
نویسنده
چکیده
For a particular set of Boltzmann weights and a particular boundary condition for the six vertex model in statistical mechanics, we compute explicitly the partition function and show it to be equal to a factorial Schur function, giving a new proof of a theorem of Lascoux.

Factorial Schur Functions and the Yang-Baxter Equation
Factorial Schur functions are generalizations of Schur functions that have, in addition to the usual variables, a second family of “shift” parameters. We show that a factorial Schur function times a deformation of the Weyl denominator may be expressed as the partition function of a particular statistical-mechanical system (six-vertex model). The proof is based on the Yang-Baxter equation. There...
متن کاملTokuyama's Identity for Factorial Schur $P$ and $Q$ Functions
A recent paper of Bump, McNamara and Nakasuji introduced a factorial version of Tokuyama’s identity, expressing the partition function of six vertex model as the product of a t-deformed Vandermonde and a Schur function. Here we provide an extension of their result by exploiting the language of primed shifted tableaux, with its proof based on the use of non-intersecting lattice paths.

متن کاملProducts of Schur and Factorial Schur Functions
The product of any finite number of Schur and factorial Schur functions can be expanded as a Z[y]-linear combination of Schur functions. We give a rule for computing the coefficients in such an expansion which generalizes the classical Littlewood-Richardson rule.
متن کاملA Littlewood-Richardson Rule for factorial Schur functions
We give a combinatorial rule for calculating the coe cients in the expansion of a product of two factorial Schur functions. It is a special case of a more general rule which also gives the coe cients in the expansion of a skew factorial Schur function. Applications to Capelli operators and quantum immanants are also given.
