On the binomial edge ideals of proper interval graphs

Abstract

We prove several cases of the Betti number conjecture for the binomial edge ideal JGJ_G of a proper interval graph GG (also known as closed graph). Namely, we show that this conjecture is true for the linear strand of JGJ_G, and true in general for any proper interval graph GG such that the regularity of S/JGS/J_G equals two.
