A **Torus action** refers to the action of a torus (typically a compact, connected Lie group isomorphic to the product of several circles, denoted as \\(T^n\\), where \\(n\\) is the number of circles) on some space, often a manifold. This concept arises in various areas of mathematics, including differential geometry, algebraic geometry, and symplectic geometry.
