Castelnuovo-Mumford regularity and Ratliff-Rush closure
Speaker: Ngo Viet Trung

Time: 9h00, Wednesday, April 1, 2015

Location: Room 6, Building A14, Institute of Mathematics, 18 Hoang Quoc Viet, Cau Giay, Hanoi

Abstract:  We establish relationships between the Castelnuovo-Mumford regularity of standard graded algebras and the Ratliff-Rush closure of ideals, which allow us to compare the regularities of the Rees algebra and the fiber ring of  homogeneous ideals generated by forms of the same degree.

(It is a joint work M. E. Rossi, N.V.Trung and  and D.T.Trung).
