Multiplicative structure of 2x2 tropical matrices

Group Theory 2009-07-03 v1

Abstract

We study the algebraic structure of the semigroup of all 2×22 \times 2 tropical matrices under multiplication. Using ideas from tropical geometry, we give a complete description of Green's relations and the idempotents and maximal subgroups of this semigroup.
