    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

        Maybe they put him in the dryer with the sheets. My duvet cover is like some kind of Bag of Holding that swallows pillow cases and never wants to return them.

    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

    Wow, I had no idea the Calabi-Yau Manifold was a real thing. I thought it was just made up for Barotrauma, since that was the only place I heard of it. It sounded Lovecraftian enough so I never questioned it lol

      There’s a great book by Greg Egan called Diaspora that explores the idea that every atom is a Calabai-Yau manifold, and the aperture to a wormhole via Kaluza-Klein handwavery. It’s a bit of a heavy read at times but super interesting.
