Suppose that $(A,\mathfrak{m})$ is a complete intersection and $\mathbf{x}$ is a minimal basis for $\mathfrak{m}$. Consider the Koszul homologies $H_\bullet(\mathbf{x},A)$. It is well-known that $\text{Vdim}_{K}(H_1(\mathbf{x},A))=\text{embdim}(A)-\text{dim}(A)$. My question is that do we have some information about the vector space dimension of the second Koszul homology $H_2(\mathbf{x},A)$? Something different from the Euler-Poincare characteristic which says that the sum of length of Koszul homologies vanishes.
