1. Canonical modules of Rees algebras

Author

Abstract

Abstract: We compute the canonical class of certain Rees algebras. Our formula generalizes that of Herzog and Vasconcelos. Its proof relies on the fact that the formation of the canonical module commutes with subintersections in important cases. As an application we treat the classical determinantal ideals and the corresponding algebras of minors. [Copyright &y& Elsevier]

2. Minors of symmetric and exterior powers

Author

Bruns, Winfried and Vasconcelos, Wolmer V.

Subjects
*ALGEBRAIC surfaces, *ALGEBRA
Abstract

We describe some of the determinantal ideals attached to symmetric, exterior and tensor powers of a matrix. The methods employed use elements of Zariski''s theory of complete ideals and of representation theory. [Copyright &y& Elsevier]
