Combinatorial rigidity of 3-dimensional simplicial polytopes
Suyoung Choi, Jang Soo Kim
A simplicial polytope is combinatorially rigid if its combinatorial structure is determined by its graded Betti numbers which are important invariant coming from combinatorial comm…

A combinatorial proof of a formula for Betti numbers of a stacked polytope
Suyoung Choi, Jang Soo Kim
For a simplicial complex , the graded Betti number of the Stanley-Reisner ring over a field has a combinatorial interpretation due to Hochster. Terai…
