On the Vanishing and the Finiteness of Supports of Generalized Local Cohomology Modules
Nguyen Tu Cuong, Nguyen Van Hoang
Let $(R,\fr m)$ be a Noetherian local ring, an ideal of and two finitely generated -modules. The first result of this paper is to prove a vanishing theorem for ge…
On Sequentially Cohen-Macaulay Modules
Nguyen Tu Cuong, Doan Trung Cuong
In this paper we present characterizations of sequentially Cohen-Macaulay modules in terms of systems of parameters, which are generalizations of well-known results on Cohen-Macaul…
Hilbert polynomials of non-standard bigraded algebras
Nguyen Duc Hoang, Ngo Viet Trung
This paper is a systematic study of the Hilbert polynomial of a bigraded algebra R which are generated by elements of bidegrees (1,0), (d_1,1),...,(d_r,1), where d_1,...,d_r are no…
Constructive characterization of the reduction numbers
Ngo Viet Trung
We present a constructive description of minimal reductions with a given reduction number. This description has interesting consequences on the minimal reduction number, the big re…
