Titles and Abstracts
Scope and Topics:
In the last 15 years tremendous progress has been made at connecting integrable four-dimensional gauge theory and two-dimensional world-sheet theory. A two-dimensional integrable model was constructed that can predict not only the spectrum of energy levels, to unprecedented precision, but also permit the computation of the correlation functions of the theory at finite coupling in the planar limit.
This workshop will be devoted to discussing important and timely problems concerning the application of exact mathematical methods to conventional integrable systems and to the gauge/string models, e.g., to extend current methods for calculating finite-volume matrix elements of operators, to construct a finite version of the hexagon form factor expansion for short operators, to extend the methods of the thermodynamic Bethe Ansatz to world-sheets of higher topology and to all sorts of boundaries and defects, etc.
Students and young scientists, both theoretical physicists and mathematicians, interested in integrability are encouraged to participate. Lectures for students and non-specialists are planned in view of improving the research capacity of the Bulgarian scientists.

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 (for tourist info see here).
The Guest House is in resort "Chaika" which is situated in the beach resort area extending to the
north-east of Varna between two of Bulgaria's biggest coastal resorts "St. Constantine and Elena" (formerly "Druzhba") and "Golden Sands".
Besides the Guest House alternative accommodation is possible in near-by hotels, e.g., Park-hotel "Zdravets" (very near to the Guest House across the street).
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 22 km (10 km) from the
Conference site with direct bus connection - see overall map
For a detailed map of the neighbourhood of the Guest House click
here. This second
map shows the Guest House (on the map it is called: "Pochivna baza BAN"),
Park-hotel Zdravets (on the map it is called: "Hotel Zdravets-1"), and
the House of Journalists (on the map it is called: "Hotelski Kompleks Zhurnalist"),
in front of the latter is the nearest bus stop to the Guest House. This bus stop is for bus # 409.
The Guest House is 100m uphill from this stop.
A card on the whereabouts of the Guest House in Bulgarian (also translated) which may be shown to
taxi-drivers is here.
Note that bus # 409 is a bus line from
Varna airport to "Golden Sands" stopping also at the Varna bus station.
(Note that on the overall map is shown only bus # 9, which is a bus line from Varna railway station
(direction "Golden Sands") and which bypasses the stop at the House of Journalists.)
Taxis are cheap in principle (around 1.1 Lev per km)
but the taxi-drivers may try to cheat you! Insist on the counter (meter) running and pay by what it shows!
To avoid misunderstandings as on previous occasions
we shall use the taxi company "Omega-Trans", its cars are marked
also with the capital Greek letter 'Omega'.
Upon your arrival at the airport AFTER RECEIVING your luggage you
may order a taxi from the airport to the Guesthouse of the Academy
of Sciences calling one of the following numbers: +359-52-388-888,
+359-888-388-888, +359-898-388-888, +359-878-388-888
Make sure that your cell-phone has roaming for Bulgaria.
Usually the taxi will arrive within 10 minutes.
Payment in principle is in Bulgarian Lev, though some taxi-men take
also euro in ratio 1 Euro = 2 Lev (the official rate being 1 Euro =
1.9558 Lev). You can get Levs from any cash machine at the airport,
but you should not change Euro at the Change Bureaus - their rate
In all cases it is advisable to send in advance the date & time of
your arrival and the number of your flight to the member of the
Organizing Committee Dr. Todor Popov, firstname.lastname@example.org.
Note that at the airport exit there are many other taxis from
different companies so make sure that the car you take is really a
taxi sent from OMEGA-TRANS. If not you are running the risk of
Registration. Deadline: 25 June 2022
