Recently, there has been a growing interest in classification of quantum field theories (QFTs) using algebraic topology. Among all QFTs, invertible ones are the most basic class to study. Their classification is important because they arise in condensed matter physics as well as the study of anomaly. These theories are nicely classified by generalized cohomology theories. In this talk, I will give an overview of this topic and explain my related works on Anderson dual cohomology theories (joint work with Kazuya Yonekura) and an application to anomaly in heterotic string theory (joint work with Yuji Tachikawa).
