Speaker:Lê Tuấn Hoa

Time: 9h00, Wednesday, November 5, 2014

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

Abstract: This is a on going work with Le Xuan Dung (Hong Duc University) and J. Elias (Barcelona). In this talk, two new bounds for the Hilbert coefficients $e_1,\ e_2$ of an $m$-primary ideal in a local Cohen-Macaulay ring $(A,m)$ in terms of $e_0$ and the order of the ideal are presented.  We also give characterization for  the bounds to be attained.
