Deterministic polynomial identity testing
Webis a deterministic polynomial identity test for multilinear read-k formulae of size sthat runs in time poly(s). In addition, there is a deterministic blackbox test that runs in time sO(logs). Note that Theorem 1.1 extends the class of formulae that Shpilka and Volkovich could handle since a sum of read-once formulae is always multilinear. WebSchwartz–Zippel lemma.
