6 During the 80-90s of the XX century, Vict or Isaakovich Ogievet sky with colleagues achieved essential progress in understanding of the m athem atical structure of supersym m etric theories. They suggested and worked out the harm onic superspace m ethod which is now widely recognized as an adequate approach to the theories with extended supersym m etry.

7 At the end of the fifties, at the suggestion of Nikolai Nikolaevich Bogoliubov Vadim Georgievich Soloviev studied the properties of deform ed nuclei in the fram ework of the m odel of independent quasiparticles. These investigations culm inated at the end of the seventies in the creation of the quasiparticle-phonon nuclear m odel. Investigations by the Soloviev's group stim ulated experim ental studies in nuclear spectroscopy at JINR in Dubna and in JINR Mem ber States and are now widely used in data analysis.

11 THEORETICAL PHYSICS Scientific personnel of the Bogoliubov Laboratory of Theoretical Physics has accum ulated extensive experience of research in several fundam ental areas of theoretical physics: quantum field theory and elem entary particle physics, theory of atom ic nuclei, condensed m atter physics and m ethods of m athem atical physics. Distinctive features of research at BLTP are the interdisciplinary character of investigations, their direct integration into international projects in cooperation with scientists from the world leading research centres, close coordination of theoretical investigations with experim ental program s of JINR.

12 Traditionally, the Laboratory has also played the role of the training centre for young scientists and students from m any countries. This activity has becom e even m ore pronounced during the last decade due to launching the scientific and educational project «Dubna International Advanced School of Theoretical Physics» (DIAS-TH), as well as opening the new departm ents of theoretical physics at Moscow Physical Technical University and Dubna International University closely associated with the Laboratory and JINR University Centre. The Laboratory has becom e a popular site for organization of international conferences, workshops, schools for young scient ist s in various fields of t heoret ical physics.

Quant um Field Theory and Part icle Physics: priorities will be determ ined by the physics program m es of m ajor international projects (LHC, RHIC, FAIR, K2K, etc.) and t he NICA/M PD project at JINR. Nuclear Theory. The m ain stream of nuclear studies at lowenergies will be the properties of nuclei far from the valley of stability. The JINR project DRIBS as well as several already established or planned experim ental projects in Europe, United States and Japan have as their m ain goal the study of unstable nuclei.

The m ajor focus of the program is the analysis of the strongly correlated electron system s novel cooperative phenom ena, new form s of order, low-dim ensional m agnetism and quantum criticality. Extensive experim ental investigations of these m aterials perform ed by neutron scattering m ethods at the Laboratory of Neutron Physics at JINR strongly m otivate the developm ent of theoretical investigations.

The overall objective of the project «Dubna International School of Theoretical Physics (DIAS-TH)» will be a prom ot ion of educat ional and t raining program s at JINR in the field of t heoret ical physics.
