Solving Schubert Problems with Littlewood-Richardson Homotopies

open access: yes, 2010
We present a new numerical homotopy continuation algorithm for finding all solutions to Schubert problems on Grassmannians. This Littlewood-Richardson homotopy is based on Vakil's geometric proof of the Littlewood-Richardson rule. Its start solutions are

Rare nonleptonic $\bar{B}_s^0$ decays as probes of new physics behind $b\to s\mu\bar\mu$ anomalies

open access: yes, 2019
The anomalous results of recent measurements on various $b\to s\mu^+\mu^-$ processes could be initial evidence of physics beyond the standard model (SM).

The Coolidge-Nagata conjecture holds for curves with more than four cusps [PDF]

open access: yes, 2012
Let E be a plane rational curve defined over complex numbers which has only locally irreducible singularities. The Coolidge-Nagata conjecture states that E is rectifiable, i.e.

Correspondences between projective planes [PDF]

open access: yes, 2014
We characterize integral homology classes of the product of two projective planes which are representable by a subvariety.Comment: Improved readability, 14 ...

Projected Gromov-Witten varieties in cominuscule spaces

open access: yes, 2017
A projected Gromov-Witten variety is the union of all rational curves of fixed degree that meet two opposite Schubert varieties in a homogeneous space X = G/P.

Galois groups of Schubert problems via homotopy computation

open access: yes, 2007
Numerical homotopy continuation of solutions to polynomial equations is the foundation for numerical algebraic geometry, whose development has been driven by applications of mathematics.

Grassmann defectivity \`a la Terracini

open access: yes, 2001
This work is a modern revisitation of a classical paper by Alessandro Terracini, going back to 1915, which suggests an elementary but powerful method for studing Grassmann defective varieties.
