Del Pezzo surfaces of degree one and examples of Zariski multiples: Computational Data

This repository contains the following three items:

1. The preprint
Ichiro Shimada, “Del Pezzo surfaces of degree one and examples of Zariski multiples” (PDF).
2. A document titled
“Del Pezzo surfaces of degree one and examples of Zariski multiples: Computational data” (PDF),
which explains the structure and contents of the data below.
3. A ZIP archive
compdata.zip,
which contains the computational data used in the preprint, mainly consisting of data on the 240 lines on del Pezzo surfaces of degree one

These materials provide examples of Zariski N-tuples with large N,  constructed using the monodromy action of the Weyl group of type E_8 on the lines in a del Pezzo surface of degree one.
