摘要：

According to Cappell and Shaneson, very often the secondary surgery obstruction Oz to codimension two splitting is zero, but examples with O-2 not equal 0 exist. By considering homotopy equivalences with codomain the total space of a two disk bundle, we produce many examples with O-2 not equal 0 and other examples with O-2 = O. Our approach is: ''compare with codimension one splitting''.
