Tensor Analysis

Definition

Geometric analysis is a field that blends differential geometry and mathematical analysis to study geometric problems using analytical techniques. It involves the examination of various geometric structures, often through the lens of curvature, metrics, and various operators to understand properties like shape, size, and curvature of manifolds.
