Mathematical valentine

This curve was described by Taubin in 1993.


(x2 + (9/4)y2 + z2 – 1)3x2z3 – (9/80)y2z3 = 0

Though I prefer the 2 dimensional form


(x2 + y2 – 1)3x2y3 = 0

  1. "Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres." (1 Corinthians 13:4-7)

    In case you have forgotten,
    Remember Valentine's Day,
    Give cards, candy or flowers,
    And celebrate it every day!

    Happy Valentine’s Day!

  2. Oh cheers Bethyada :)

    Roses are red.
    Violets are approximately blue.
    A paracompact manifold with a Lorentzian metric,
    can be a spacetime, if it has dimension greater than or equal to two
