Use for questions about mirror symmetry in theoretical/mathematical physics. Associate with [tag:mathematical-physics] if necessary.

In algebraic geometry and theoretical physics, mirror symmetry is a relationship between Calabi–Yau manifolds and refers to a situation where two Calabi–Yau manifolds look very different geometrically but are actually equivalent when employed as extra dimensions of string theory. Mathematically, it describes a correspondence between complex geometry and symplectic geometry.
