On Some Properties of LCM-Lattices of Edge Ideals of k-Uniform Hypergraphs
Muneeba Mansha, Sarfraz Ahmad
In this article, we investigate the combinatorial and algebraic properties of the lcm-lattice associated with the edge ideal of a hypergraph. Let $\H$ be a hypergraph, its…
On partial barycentric subdivision
Sarfraz Ahmad, Volkmar Welker
The lth partial barycentric subdivision is defined for a (d-1)-dimensional simplicial complex Δand studied along with its combinatorial, geometric and algebraic aspects. We analyze…
F-ideals of degree 2
G. Q. Abbasi, Sarfraz Ahmad, Imran Anwar +1
In this paper, we introduce the concept of f-ideals and discuss its algebraic properties. In particular, we give the characterization of all the f-ideals of degree 2.
Inclusion Ideals Associated to Uniformly Increasing Hypergraphs
Sarfraz Ahmad, Imran Anwar, Azeem Haider +1
In this paper,we introduce the monomial ideals I(H) associated to a special class of non uniform hypergraphs H(X; E; d) namely uniformly increasing hypergraphs. These ideals are na…
Stanley Decompositions and Polarization
Sarfraz Ahmad
We define nice partitions of the multicomplex associated to a Stanley ideal. As the main result we show that if the monomial ideal is a CM Stanley ideal, then is a Stanle…
Sequentially Cohen-Macaulay monomial ideals of embedding dimension four
Sarfraz Ahmad, Dorin Popescu
Let be a monomial ideal of the polynomial ring over a field . Then is sequentially Cohen-Macaulay if and only if is pretty clean. In particula…
