Semigroup identities of supertropical matrices
Published 13 Nov 2019 in math.RA and math.CO | (1911.05654v1)
Abstract: We prove that, for any $n$, the monoid of all $n \times n$ supertropical matrices extending tropical matrices satisfies nontrivial semigroup identities. These identities are carried over to walks on labeled-weighted digraphs with double arcs.
