Abstract
Let (A,B) be a pair of skew-symmetric matrices over a field of characteristic not 2. Its regularization decomposition is a direct sum(A__,B__)â(A1,B1)ââ¦â(At,Bt) that is congruent to (A,B), in which (A__,B__) is a pair of nonsingular matrices and (A1,B1),â¦,(At,Bt) are singular indecomposable canonical pairs of skew-symmetric matrices under congruence. We give an algorithm that constructs a regularization decomposition. We also give a constructive proof of the known canonical form of (A,B) under congruence over an algebraically closed field of characteristic not 2.
