unusual facts about Calabi–Yau manifold



Calabi conjecture

Calabi transformed the Calabi conjecture into a non–linear partial differential equation of complex Monge–Ampere type, and showed that this equation has at most one solution, thus establishing the uniqueness of the required Kähler metric.

Complex manifold

A Calabi–Yau manifold can be defined as a compact Ricci-flat Kähler manifold or equivalently one whose first Chern class vanishes.

Flop-transition

On the other hand, Mirror symmetry allows for the mathematical similarity between two distinct Calabi-Yau manifolds.
