Res($\oplus$) is the simplest fragment of $\text{AC}^0[2]\text{-Frege}$ for which no super-polynomial lower bounds on the size of proofs are known. Bhattacharya and Chattopadhyay [BC25] recently proved lower bounds of the form $\exp(\tilde\Omega(N^{\varepsilon}))$ on the size of Res($\oplus$) proofs whose depth is upper bounded by $O(N^{2 - \varepsilon})$, where $N$ is ... more >>>

Recently, Göös et al. (2024) showed that Res ? uSA = RevRes in the following sense: if a formula $\varphi$ has refutations of size at most $s$ and width/degree at most $w$ in both Res and uSA, then there is a refutation for $\varphi$ of size at most $poly(s·2^w)$ in ... more >>>
