Introduction to Toric Geometry
by Chiara Meroni and Simon Telen
This webpage contains code accompanying a series of lectures given by Simon Telen at the Max Planck Institute for Mathematics in the Sciences in Leipzig. Addressed topics include affine and projective toric varieties, abstract normal toric varieties from fans, divisors on toric varieties and Cox’s construction of a toric variety as a GIT quotient. We emphasize the role of toric varieties in solving systems of polynomial equations and provide many computational examples using the Julia package Oscar.jl. For more details on the course, click here.
For an explanation we refer to Example 3.54 in the text.
The code is presented as a Jupyter notebook in Julia which can be downloaded here:
