Abstract–
In this paper we characterize those surjective linear transformations of tropical matrices preserving the set of all weak transitive closures and the set of all strong transitive closures , respectively. We illustrate that there exist non-surjective linear transformations that preserve or . Also, we consider the strongly linear preservers of and , respectively.
