Source abstract
Abstract In this paper, we determine the sharp threshold for universality of cokernels of random matrices over finite fields. More precisely, we prove the following: given any constant , let be a sequence of random matrices over such that, for all sufficiently large , the entries of are independent and take any given value of with probability at most . Then the cokernels of converge in distribution, as , to the same limiting law as the cokernels of uniform random matrices over . This answers an open problem posed by Wood.
