XV. International Workshop




19 - 25 June 2023, Varna, Bulgaria

Scope and Topics:

The meeting covers the whole field of Lie Theory in its widest sense together with its applications in many facets of physics. As interface between mathematics and physics the workshop serves as a meeting place for mathematicians and theoretical and mathematical physicists.
The first three workshops were organised in Clausthal (1995,1997,1999), the 4th, 6th and 12th were part of the 2nd, 4th, 10th Symposium 'Quantum Theory and Symmetries' in Cracow (2001), Varna (2005, 2017), the 5th, 7th to 11th, 13th were organised in Varna (2003,2007-2015,2019), the 14-th was on-line in Sofia (2021), for more details of the LT series see: http://theo.inrne.bas.bg/~dobrev/

Monday, June 19: Arrival and registration in the afternoon
Tuesday, June 20: Talks begin in the morning
Saturday, June 24: Talks end in the late afternoon
Sunday, June 25: Departure

Conference Site and Travel:

The Conference site is situated in the beach resort area extending to the north-east of Varna on the Black Sea Coast. Varna is Bulgaria's third largest city and main naval port. The most convenient way to travel from abroad is by plane to Varna airport. In the summer there are many regular (daily) flights to Varna from many European cities and regular daily flights from Sofia (Bulgaria's capital). The latter is connected with Europe's major cities by regular daily flights. Travel by train is to Varna railway station. Detailed travel information will be given later.


The registration procedure will be announced in late-February/early-March 2023, the registration deadline will be about two months later.
