Black Moon, meet the end of Ramadan. A rare type of moon will generate a solar eclipse on April 30 just ahead of one of the largest festivals in the Muslim calendar: Eid Al-Fitr, the end of the holy month of fasting. Depending on the first sighting of the crescent moon phase, Eid falls on May 1 or May 2 this year.

    Уважаемые коллеги!

    На заседании Ученого совета в пятницу 29 апреля в 11:30 будут заслушаны
    2 доклада:

    1) A. Litvinov
    *Affine Yangian of gl(2) and integrable structures of superconformal
    field theory*

    We study of integrable structures in superconformal field theory and
    more general coset CFT's related to the affine Yangian
    Y(\hat{\mathfrak{gl}}gl^​(2)). We derive the relation between the RLL
    and current realizations and prove Bethe anzatz equations for the
    spectrum of Integrals of Motion.


    2) A. Litvinov
    *On loop corrections to integrable 2D sigma model backgrounds* (короткий
    доклад)

    We study regularization scheme dependence of β-function for sigma models
    with two-dimensional target space. Working within four-loop
    approximation, we conjecture the scheme in which the β-function retains
    only two tensor structures up to certain terms containing ζ_{3}3​. Using
    this scheme, we provide explicit solutions to RG flow equation
    corresponding to Yang-Baxter- and λ-deformed SU(2)/U(l) sigma models,
    for which these terms disappear.
