Abstract
We introduce a notion of equivariant vector bundles on schemes over semirings. We do this by considering the functor of points of a locally free sheaf. We prove that every toric vector bundle on a toric scheme over an idempotent semifield equivariantly splits as a sum of toric line bundles. We then study the equivariant Picard group . Finally, we prove a version of Klyachko's classification theorem for toric vector bundles over an idempotent semifield.
