Vectors of matroids over tracts

Abstract

We enrich Baker and Bowler's theory of matroids over tracts with notions of vectors and covectors. In the case of oriented matroids, these FF-vectors and FF-covectors coincide with the usual signed vectors and signed covectors. In the case of matroids over a field FF, the FF-covector set resp. FF-vector set of an FF-matroid is a linear subspace of FEF^E resp. its orthogonal complement.
