Mirror Symmetry Conjecture

Definition

The Mirror Symmetry Conjecture is a central concept in both algebraic geometry and string theory, proposing a deep relationship between two seemingly different geometric spaces called mirror manifolds. It suggests that certain invariants associated with one manifold can be reflected in the other, leading to a correspondence between the two worlds. In the context of tropical geometry, this conjecture plays a significant role in understanding tropical Gromov-Witten invariants, providing insights into enumerative geometry and deformation theory.
