In this talk, we follow the book ‘Fourier Integral Operators’ by Duistermaat. Fourier integral operators (FIO) are a class of operators that generalise pseudodifferential operators. While pseudodifferential operators include solution operators to elliptic problems, FIO include solution operators to genuinely non-elliptic problems, making them a natural object of study. We will discuss some basic properties of FIO and prove some key technical results.
