Abstract: We apply the Izergin‐Korepin analysis to the study of the projected wavefunctions of the generalized free‐fermion model. We introduce a generalization of the L‐operator of the six‐vertex model by Bump‐Brubaker‐Friedberg and Bump‐McNamara‐Nakasuji. We make the Izergin‐Korepin analysis to characterize the projected wavefunctions and show that they can be expressed as a product of factors and certain symmetric functions which generalizes the factorial Schur functions. This result can be seen as a generalization of the Tokuyama formula for the factorial Schur functions.
