Tropical rank is defined in terms of determinant in the literature. I will introduce a rank in terms of linear dependence and show it equals the tropical rank. This fact is nontrivial because we do not have row reduction which is a key tool to prove the equality for matrices over fields. This talk is based on the paper "the tropical rank of a tropical matrix" written by Z. Izhakian.
