Abstract
We investigate the minimal free resolutions of cyclic modules $R/I$, where $I$ is an almost complete intersection in the local ring $R$. Our results concern various binomial lower bounds for the Betti numbers of the resolution. For example, we show that the sum of the Betti numbers is at least $2^{d}$ where $d$ is the dimension of $R$.
