3:45PM: CastelnuovoMumford regularity of power productsWinfried BrunsWe show that the CastelnuovoMumford regularity and re lated invariants of products of powers of ideals in a standard graded polynomial ring are affinelinear in the exponents if these are large enough, provided that each ideal is generated by elements of constant degree. A counterexample shows that linearity is false without the con dition, but the regularity is always given by the maximum of finitely many affinelinear polynomials. This is joint work with Aldo Conca (Genoa).
