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 for questions which attract longer answers.

## 1 Questions

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

How does one prove that ?
