Abstract
We continue to study the rank functions of tropical matrices. In this paper, we explain how to reduce the computation of ranks for matrices over the `supertropical semifield' to the standard tropical case. Using a counting approach, we prove the existence of a -matrix with many ones and without large all-one submatrices, and we put our results together and construct an matrix with tropical rank and Kapranov rank .
