General Information

Since the 6th Workshop in 2018, we witnessed a rapid development in the field of combinatorial methods in application to geometry and mathematical physics. We are observing inter-proliferation of two main subjects traditionally presented in the workshop agenda—cluster algebras and topological recursion. It is tempting to see how these two topics can be unified within the mirror symmetry framework, how spectral curves obtained from Landau-Ginzburg potentials motivated by cluster algebras can arise within the classical and quantum topological recursion, and how it all can be interpreted in cohomological field theory framework and be applied to knot theory and knot invariants. Notable is also a modern development of cluster structures in Lie algebras, including classical and quantum algebras of monodromies of Fuchsian systems, and other fascinating topics related to clusters and topological recursion including a modern treatise of Masur-Veech volumes.

In order to accommodate in a best possible way our worldwide spread community, including our friends from Australia and East Asia, we schedule only three lectures every day from Monday, May 31, till Friday, June 4, from 8am to 11am (East Coast time; 2pm to 5pm in continental Europe or 3pm to 6pm Moscow). We apologize to our friends on West Coast and Alberta for possibly early hours. Lectures will be recorded and available online. Thursday is reserved for (shorter, 30-minute long) presentations of younger researchers. The last lecture on Tuesday will be the last talk by Bertrand Eynard on the online Topological Recursion seminar.

The main theme of workshop this year will be interrelations between topological and geometrical recursion and cluster algebras. The main topic will be structures appearing in generalizations of topological recursion and cluster algebras to non-orientable surfaces and supersymmetry.

Also, if you’ve got this mail, there is NO NEED to make registration; all registered participants of MoSCATR VII in 2020 are automatically re-registered to its online version (which means that we’ll supply you with all relevant information, including zoom codes for lectures). Of course, you may opt for excluding yourself from this distribution list; for this, just reply to this email.

We’ll also include all register participants of the online Topological Recursion seminar into the list of distribution for the workshop; if you know people who are interested in workshop but are not participants of either TR seminar or a conference 2020, feel free to recommend them to make a registration on the site (some questions there may look weird but it is just a standard questionary at HSE, which we cannot change by formal reasons; if someone doesn’t want to correspond, say, the date of birth, just submit smth like 01.01.2000).
