    WARNING: If your compact Kähler manifold whose first Chern class is vanishing is also Ricci-flat, then it is a Calabi-Yau. Proceed with care.

    • Risk of non-Riemaniann metric
    • Holonomy equal to a subgroup of SU(n)
    • Possibility of mild singularities

    I used to see a local band named Calabi-yau. Their sound was kind of a rush-inspired math-rock. Really talented guys. Guitar player got hired by google and moved so the group kind of retired
