### Special Issue on Representation Theory and Integrable Systems in honor of Vitaly Tarasov on the 60th birthday and Alexander Varchenko on the 70th birthday

The Guest Editors for this special issue are

Pavel Etingof (Massachusetts Institute of Technology, USA)
Giovanni Felder (ETH Zürich, Switzerland)
Evgeny Mukhin (Indiana University - Purdue University Indianapolis, USA)

The issue will be dedicated to the study of integrable systems which naturally appear in the representation theory and related questions. In particular, topics for this special issue will include:

• Gaudin, XXX, XXZ, XYZ models and their affine analogs;
• representations of quantum groups;
• Bethe ansatz method;
• ODE-IM correspondence;
• geometric Langlands correspondence;
• conformal field theory.

This issue is related to the conference in honor of Vitaly Tarasov on his 60th birthday and Alexander Varchenko on his 70th birthday held at ETH in Zurich, August 12–18, 2019. The speakers and participants of the conference, and other researchers whose work is directly concerned with the above topics, are invited to submit papers to the special issue. Both original research articles and review papers are welcome.

There is no limit to the length of an article. Deadline for paper submission is August 31, 2020.

All articles will go through the standard peer reviewing procedure of SIGMA.

If you have your paper ready earlier than the deadline, we encourage you to send it now. The reviewing process starts once the paper is submitted and we will publish the paper as soon as the positive publication decision is made. The paper will be indexed in the relevant databases as soon as it is published without waiting for completion of the special issue.
