Abstract
In this paper we characterize those linear bijective maps on the monoid of all n×n square matrices over an anti-negative semifield (that is, a semifield which is not a field) which preserve each of Green's equivalence relations L, R, H, D, J and the corresponding four pre-orderings ≤L, ≤R, ≤H, ≤J. These results apply in particular to the tropical and boolean semirings.
