Products of Factorial Schur Functions

V. Kreiman

Published 2007-12-31, updated 2008-03-04Version 2

The product of any finite number of 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 a specialization of the Molev-Sagan rule, which in turn generalizes the classical Littlewood-Richardson rule.

Comments: 10 pages; v2: result generalized slightly, references added, minor corrections in section 4
