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/

Conference Site:

The Workshop will take place at the Guest House of the Bulgarian Academy of Sciences on the Black Sea coast near Varna. Varna is Bulgaria's third largest city and main naval port. The participants who booked accommodation through the Organizing Committee will be accommodated in the Guest House or in the neighbouring hotel "Vezhen". The latter participants will have breakfast at their hotel, lunch and dinner at the Guest House. The Guest House is in resort "Chayka" which is situated between two of Bulgaria's biggest coastal resorts "St. Constantine and Elena" (formerly "Druzhba") and "Golden Sands".

Travel information:

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. The airport (railway station) is about 22 km (10 km) from the Conference site with direct bus connection. .
