Homological invariants of edge ideals of the multiple extended complete split-like graphs
Bilal Ahmad Rather
We study the graphs $MECS_{b,n}^a \cong \overline{K}_a \join \big(n(K_b+K_2)\big)$, obtained by attaching an independent set of size to disjoint copies of the block $K_b+K_…

Betti numbers for cochordal zero-divisor graphs of commutative rings
Bilal Ahmad Rather
This paper studies the zero-divisor graphs attached to several finite chain-ring families and computes the homological invariants of their edge ideals by using cochordal constructi…
