Given two matroids on the same ground set, the matroid intersection problem asks to find a common independent set of maximum size. We show that the linear matroid intersection problem is in quasi-NC2. That is, it has uniform circuits of quasi-polynomial sizenO(logn), andO(log2n) depth. This generalizes the similar result for the bipartite perfect matching problem. We do this by an almost complete derandomization of the Isolation lemma for matroid intersection.Our result also implies a blackbox singularity test for symbolic matrices of the formA0+A1z1+A2z2+ …+Amzm, whereA0is an arbitrary matrix and the matricesA1,A2,…,Amare of rank 1 over some field.
