On 10 February, the International Workshop on Problems of Modern Mathematical Physics (PMMP’25) started at the Laboratory of Theoretical Physics at JINR. More than 75 specialists from Armenia, Bulgaria, China, Russia, and Serbia are taking part in the event.

Director of the Laboratory of Theoretical Physics at JINR Dmitry Kazakov opened the meeting and wished the participants fruitful work. “Events like this are really important for the development of international scientific cooperation,”— Dmitry Kazakov emphasised. “I hope that during these five days, you will get to personally see how our Laboratory lives, to meet and talk to our scientists.”

In addition, JINR Vice-Director Latchesar Kostov addressed the participants with a welcome speech. He noted that today it is especially important to maintain scientific contacts and establish new ties. “This annual meeting is intended to become the starting point for a new fruitful cooperation,” Latchesar Kostov said. “I am convinced that scientific partnership is currently one of the most important tools for solving global problems.”

On the first day of the meeting, Professor at St. Kliment Ohridski Sofia University (Bulgaria) Radoslav Rashkov presented an overview of the latest results in the study of various aspects of holographic correspondence and conformal field theories. In addition, during the plenary meeting, Chief Researchers at the Laboratory of Theoretical Physics at JINR Evgeny Ivanov and Nikolai Krasnikov delivered presentations entitled “Harmonic superspace in action: unravelling N = 2 higher spins” and “Bounds on the invariant charges in QED and QCD”. Professor at the Mathematical Institute of the Serbian Academy of Sciences and Arts (MISANU, Serbia) Branko Dragovich spoke about simple nonlocal de Sitter gravity model.

According to the programme of the event, more than 50 presentations covering a wide range of research areas will be presented. The participants will discuss the following topics:

• mathematical physics;
• gravity;
• integrable systems;
• supersymmetry;
• higher spin theories.

The International Workshop on Problems of Modern Mathematical Physics (PMMP’25) will be held for five days, until 14 February. The event’s programme is available via the link. The working languages of the workshop are English and Russian.
