Regularity of Symbolic Powers of Co-Chordal Edge Ideals
Chwas Ahmed, Mohammed Rafiq Namiq
Let be a finite simple co-chordal graph with at least one edge, and let be its edge ideal. Over an arbitrary field, we prove that the symbolic powers of satisfy $…
Betti Numbers of Sequentially Cohen-Macaulay Co-Chordal Graphs and Their Applications
Mohammed Rafiq Namiq
We study edge ideals of sequentially Cohen-Macaulay co-chordal graphs through the maximal-clique structure of their chordal complements. After making the required construction orde…
A Complete Classification of 2-Linear Neighborhood Complexes
Mohammed Rafiq Namiq
Let be a nonempty finite simple graph. We study when the Stanley-Reisner ideal of its neighborhood complex has a -linear resolution. Combining Fröberg's theorem with the cl…
Vertex Dismissibility and Scalability of Simplicial Complexes
Mohammed Rafiq Namiq
We introduce and study strongly vertex dismissible, vertex dismissible, and scalable simplicial complexes as non-pure extensions of vertex decomposability and shellability. Strong…
Explicit Betti Numbers for Skeletons of Chordal Clique Complexes and Their Alexander Duals
Mohammed Rafiq Namiq
We study the homological properties of , a simplicial complex formed by sequentially gluing complete graphs along -simplices. This constr…
Initially Cohen-Macaulay Modules
Mohammed Rafiq Namiq
In this paper, we introduce initially Cohen-Macaulay modules over a commutative Noetherian local ring , a new class of -modules that generalizes both Cohen-Macaulay and seque…
