Rigid Analytic Geometry

Definition

Rigid analytic geometry is a branch of mathematics that studies the properties and relationships of rigid analytic spaces, which are geometric objects defined over non-Archimedean fields, particularly p-adic fields. This area connects deeply with number theory, allowing mathematicians to explore how algebraic structures behave under rigid analytic conditions, leading to insights in various areas, such as modular forms and arithmetic geometry.
