**An Introduction to Algebraic Surgery**

by Andrew Ranicki

**Publisher**: arXiv 2000**Number of pages**: 82

**Description**:

Browder-Novikov-Sullivan-Wall surgery theory investigates the homotopy types of manifolds, using a combination of algebra and topology. It is the aim of these notes to provide an introduction to the more algebraic aspects of the theory (such as the Wall surgery obstruction groups), without losing sight of the geometric motivation.
