Regularity of powers of (parity) binomial edge ideals

In this paper, we provide exact formulas for the Castelnuovo-Mumford regularity of powers of an almost complete intersection ideal $I$ which is generated by a homogeneous $d$-sequence. As applications, when $I$ is an almost complete intersection, taking the form of the (parity) binomial edge ideal of a connected graph, we can describe explicitly formulas for $\text{reg}(I^t)$ for $t\ge 2$\mathrm{.}Theonlyexceptioniswhen$I$ is the parity binomial edge ideal of a graph which is obtained by adding an edge between two disjoint odd cycles.
