In a seminal work, Buhrman et al. (STOC 2014) defined the class $CSPACE(s,c)$ of problems solvable in space $s$ with an additional catalytic tape of size $c$, which is a tape whose initial content must be restored at the end of the computation. They showed that uniform $TC^1$ circuits are ... more >>>
Trevisan and Vadhan (FOCS 2000) introduced the notion of (seedless) extractors for samplable distributions. They showed that under a very strong complexity theoretic hardness assumption (specifically, that there exists a problem in $\E=\DTIME(2^{O(n)})$ that cannot be computed by size $2^{\Omega(n)}$ circuits that have an oracle to $\Sigma_6^{\P}$) there are extractors ... more >>>
Motivated by questions concerning the multilinear and homogeneous complexity of the elementary symmetric polynomials, we prove the following results:
We first show that by making small modifications to the nonzero coefficients of the degree-$K$, $N$-variate elementary symmetric polynomial $\sigma_{N,K}$, one obtains a polynomial that can be computed by a monotone ... more >>>
