    Notes: Abstract Hermitian structures onA ∞ ring spaces are studied as necessary input data for HermitianK-theory of spaces. Especially 1/2-locally a coherence structure is derived for the involution onQ(ΩM +),M a compact manifold, arising from the stable tangent bundle. The eventual goal is to lift the rational results of Burghelea-Fiedorowicz on the relation of the space of homotopy equivalences modulo homeomorphisms ofM and hermitianK-theory to 1/2-local ones.

    Notes: Abstract This is the second of a series of papers on the HermitianK-theoryδ L(X) of anA ∞ ringX. Here we give its construction as an infinite loop space and alternative descriptions of its underlying space in terms of the Hermitian matrix ring overX. We investigate its relation to the HermitianK-theories of discrete and simplicial rings with involution and to Waldhausen'sK-theoryK(X) ofX, and its behavior under n-connected maps betweenA ∞ rings.
