Classification of topological 4-manifolds with infinite fundamental group, 2

This talk will be the second part of a survey of ideas and results related to the classification of topological 4-manifolds up to homeomorphism or s-cobordism. In this talk I will assume that the fundamental group is infinite, and discuss (i) geometrically 2-dimsnsional groups, (ii) minimal 4-manifolds with a given fundamental group, and (iii) open problems.
