Global algebraic K-theory is Swan K-theory

Abstract: We construct an equivalence between Hausmann's model of global stable homotopy theory in terms of symmetric spectra on the one hand and spectral Mackey functors in the sense of Barwick on a certain global effective Burnside category on the other hand. Using this, we then give a new description of Schwede's global algebraic $K$-theory by identifying the corresponding spectral Mackey functors with certain categorically defined Mackey functors, making precise the slogan that global algebraic $K$-theory is a coherent version of Swan $K$-theory.
