Deterministic Õ(n^{ω(σ)}) time algorithm for multi-source reachability in digraphs with n^σ sources, improving prior randomized n^{1+2/3ω(σ)} bound.
Characterizes optimal small-set expanders via girth, proves existence of s-optimal expanders, derives transfer lower bounds, and applies them to post-quantum crypto codes.
