摘要：
Let G be a simple graph on n vertices and I-G denotes parity binomial edge ideal of G in the polynomial ring S =K[x(1), ..., x(n), y(1), ..., y(n)]. We obtain lower bound for the regularity of parity binomial edge ideals of graphs. We then classify all graphs whose parity binomial edge ideals have regularity 3. We classify graphs whose parity binomial edge ideals have pure resolution.
