Q&A

What is p-adic geometry?

P-adic geometry studies geometry using p-adic numbers, introducing differential tools to understand geometric phenomena.

What are tangent bundles and tangent spaces?

Tangent bundles and tangent spaces provide a framework to analyze the behavior and properties of geometric objects at each point.
