  1. Algebraic geometry for tensor networks, matrix multiplication, and flag matroids

    Seynnaeve, TimUniversität Leipzig

    … Finally, we study the Hessian discriminant of a cubic surface, a recently introduced invariant defined in terms of the Waring rank. We express the Hessian discriminant in terms of fundamental invariants. This answers Question 15 of the 27 questions on the cubic surface posed by Bernd Sturmfels. …

  2. A Bayesian approach to computing Brauer groups of cubic surfaces

    James, Austen ARice University2022

    … an algorithm for computing the Brauer groups of cubic surfaces. The algorithm takes as input an equation for a cubic surface X and a confidence threshold 0.5 < r < 1 and outputs a candidate for the Brauer group of X and a confidence level > r for the result. The algorithm runs by sampling lifts …

  4. Double affine Hecke algebras and noncommutative geometry

    Oblomkov, AlexeiMassachusetts Institute of Technology2005

    … the spectrum of the center of H is an affine cubic surface C, obtained from a projective one by removing a triangle consisting of smooth points. Moreover, any such surface is obtained as the spectrum of the center of H for some values of parameters. We prove that the only fiat de- formations …
