A Theorem of Gruson


a presentation of M , where F is a free module of arbitrary rank. Let U denote the matrix (with n rows but possibly infinitely many columns) representing φ with respect to some fixed bases for F and An. For t ≥ 1 we let It(φ) denote the ideal of A generated by all t-sized minors U . (This ideal is independent of the choice of bases.) By convention, It… (More)
