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.
