✦ Synopsis

According to Cappell and Shaneson, very often the secondary surgery obstruction 02 to codimension two splitting is zero, but examples with 02 # 0 exist. By considering homotopy equivalences with codomain the total space of a two disk bundle, we produce many examples with 02 # 0 and other examples with 02 = 0. Our approach is: "compare with codimension one splitting".
