This page organizes questions and answers about surgery theory.

The natural first port of call for quick answers is Mathoverflow.

Below is a list of questions, possibly with answers.

The Atlas also has a chapter Questions for questions which attract longer answers.

## Contents |

## 1 Questions

### 1.1 How do I tell if a space is homotopy equivalent to a manifold?

This is in fact a Mathoverflow question.

### 1.2 Simply connected odd-dimensional L-groups

How does one prove that ?

Read [Kervaire&Milnor1963, Section 6] and/or [Browder1972, IV.3] and/or [Ranicki2002, 12.6].
