Calabi-Yau manifold

Meaning

Noun

• A kind of manifold having properties, such as Ricci flatness, that yield applications in theoretical physics.

Origin

• The name was coined by Candelas et al. (1985), after Eugenio Calabi (1954, 1957) who first conjectured that such surfaces might exist, and Shing-Tung Yau (1978), who proved the Calabi conjecture.
