Arithmetic Geometry
Adelic points are a way to study rational points on algebraic varieties by considering them in a global context using the adeles, which combine local information from various places including the archimedean and non-archimedean completions of the number field. They allow mathematicians to understand solutions to polynomial equations in a more unified manner by incorporating both local and global perspectives, which is crucial for concepts like weak approximation and arithmetic equidistribution.
congrats on reading the definition of adelic points. now let's actually learn it.
