This special issue of SIGMA is created in honor of Vitaly Tarasov on his 60th birthday and Alexander Varchenko on his 70th birthday, to celebrate their outstanding contribution to mathematics and mathematical physics.

The volume consists of 13 papers for a total of 338 pages covering a wide range of topics in geometry, representation theory, and integrable systems.

We are grateful to all the authors who contributed to this volume and to the referees for providing constructive reviews. Many of the papers were reported at the corresponding conference held at ETH in Zurich, August 12–18, 2019. We thank all the speakers and the participants for contributing to the success of the conference.
