Jiahe Wang and I (Burt Totaro) are submitting a revision of the Schubert2 package. We add functions for symmetric or skew-symmetric degeneracy loci, as well as for weighted projective spaces. (Skew-symmetric degeneracy loci are also known as Pfaffian varieties.) We include related tests and examples. Finally, we update the existing documentation for the package.
These functions are used in Wang's paper:
https://arxiv.org/abs/2606.13466
Wang generated the initial code for the functions with the assistance of ChatGPT, tested it, and revised it. I wrote the documentation.
