<div class="tex2jax_process">Arithmetic geometry lies in the intersection of number theory and algebraic geometry. It involves studying geometric objects such as curves or varieties through an arithmetic lens, e.g. via their rational points. As a research area, it dates back to classical questions such as those in Diophantine geometry, and yet continues to develop rapidly in the modern mathematical context. It is wide in scope, using a variety of techniques from algebraic geometry, algebraic and analytic number theory, and computational mathematics.
