Regularity of the vanishing ideal over a parallel composition of paths
Regularity of the vanishing ideal over a parallel composition of paths
Let G be a graph obtained by taking rā„2 paths and identifying all first vertices and identifying all last vertices. We compute the CastelnuovoāMumford regularity of the quotient SāI(X), where S is the polynomial ring on the edges of G and I(X) is the vanishing ideal of the projective toric ā¦
