Published in 2021 at "Bulletin of The Iranian Mathematical Society"

DOI: 10.1007/s41980-021-00560-4

Abstract: In this paper, we introduce the unbalanced crown graphs $${\mathcal {C}}_{m,n}$$ , and compute all graded Betti numbers of edge ideals of these graphs in terms of associated numerical data. As a consequence, we determine… read more here.
