Abstract:

Using the language of category theory and universal algebra we formalize the passage from the permutative category of finitely generated free $R$-modules to the algebraic $K$-theory $KR$ of $R$ and thus make it applicable to homotopy ring spaces. As applications we construct a Waldhausen type of algebraic $K$-theory for arbitrary homotopy ring spaces, show its equivalence with constructions of May and Steiner, prove its Morita invariance and show that the algebraic $K$-theory $KX$ of an ${E_\infty }$ ring $X$ is itself an ${E_\infty }$ ring. Finally we investigate the monomial map $Q(BX_ + ^\ast ) \to KX$.
