Symmetrized Bideterminants on Skew Shapes

Abstract. Schur modules are spanned by skew determinants, and Coschur modules are spanned by symmetrized skew determinants.

Viewed as functors from the category of commutative rings to the category of modules, Schur(\lambda/\mu) and Coschur(\lambda/\mu) are universally free functors. These and other categorical properties become trivial in the present approach.

The following version is available:
