© 2016 The Author(s)We study the problem of efficiently correcting an erroneous product of two (Formula presented.) matrices over a ring. Among other things, we provide a randomized algorithm for correcting a matrix product with at most k erroneous entries running in (Formula presented.) time and a deterministic (Formula presented.)-time algorithm for this problem (where the notation (Formula presented.) suppresses polylogarithmic terms in n and k).
