Abstract

Motivated by the description of the C*-algebra of the affine automorphism group N6,28N_{6,28} of the Siegel upper half-plane of degree 2 as an algebra of operator fields defined over the unitary dual N6,28^\widehat{N_{6,28}} of the group, we introduce a family of C*-algebras, which we call almost C0(K)C_0(\mathcal{K}), and we show that the C*-algebra of the group N6,28N_{6,28} belongs to this class.
