The homotopy category of simply connected 4-manifolds
Hans-Joachim Baues, Teimuraz Pirashvili
This study is concerned with computing the homotopy classes of maps algebraically and determining the law of composition for such maps. The problem is solved by introducing new algebraic models of a 4-manifold. Including a complete list of references for the text, the book appeals to researchers and graduate students in topology and algebra.
