Journal article Pacific Journal of Mathematics · January 1, 1982 The propose of this paper is to define numerical invariants of odd-dimensional surgery obstructions, computable in a way similar to that used to compute the index and Arf invariants of even-dimensional surgery obstructions. The main result is that a system ... Full text Cite
