[string theory] In algebraic geometry and theoretical physics, mirror symmetry is a relationship between geometric objects called Calabi–Yau manifolds. It can happen that two Calabi–Yau manifolds look very different geometrically but are nevertheless equivalent if they are employed as extra dimensions of string theory. In this case, the...
