Baker and Bowler defined a category of algebraic objects called tracts which generalize both partial fields and hyperfields. They also defined a notion of weak and strong matroids over a tract F, and proved that if F is perfect, meaning that F-vectors and F-covectors are orthogonal for every matroid over F, then the notions of weak and strong F-matroids coincide. We define the class of strongly fused tracts and prove that such tracts are perfect. We also show that both partial fields and stringent hyperfields are strongly fused; in this way, our criterion for perfection generalizes results of Baker–Bowler and Bowler–Pendavingh.
