Уважаемые коллеги!<br>
<br>
На заседании Ученого совета в пятницу 29 апреля в 11:30 будут
заслушаны 2 доклада:<br>
<br>
1) A. Litvinov<br>
<font size="4"><b>Affine Yangian of gl(2) and integrable structures
of superconformal field theory</b></font><br>
<br>
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.<br>
<br>
<br>
2) A. Litvinov<br>
<font size="4"><b>On loop corrections to integrable 2D sigma model
backgrounds</b></font> (короткий доклад)<br>
<br>
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. <br>
