Chapter Chapter 1 in Kac Algebras and Duality of Locally Compact Groups, 1992, pp 7-43 from Springer

Abstract: Abstract This chapter is devoted to the structure of co-involutive Hopf-von Neumann algebras, which has been introduced by Ernest ([44]), and mostly studied by Kirchberg ([79]), and de Cannière and the authors ([21]). The paradigm, from which the whole theory comes, is the algebra L ∞(G) of all the (classes of) essentially bounded measurable (with respect to a left Haar measure) complex valued functions on a locally compact group G,equipped with a coproduct and a co-involution, which are nothing but the duals of the usual product and involution of the involutive Banach algebra L 1 (G) of all (classes of) integrable (with respect to a left Haar measure) complex valued functions on G (let us recall that L l (G) is the predual of L ∞(G)).
