On the group rings of abelian minimax groups, II: The singular case

The main results of [D. Segal, On the group rings of abelian minimax groups, J. Algebra 237 (2001) 64–94], and of related papers by J.E. Roseblade and C.J.B. Brookes, are extended to group rings kG where the characteristic of the field k occurs in the spectrum of the abelian minimax group G.
