I will discuss several classical problems in number theory about representation of numbers and forms by quadratic forms and related counting results. We will describe several applications such as pair correlations and eigenvalue statistics for quantum systems.
Then we will move to related problems about irrational forms, such as the Oppenheim conjecture and explain how homogeneous dynamics can help to tackle such problems.
The talk will be self contained and hopefully accessible.
