*2nd of December*

*2019 , 17:00*the AMU regular meeting will take place at the YSU,

faculty of Mathematics and Mechanics (room 241).

**Prof . Alexey Karapetyants**from the Southern Federal University (Rostov-on-Done), Russia will give a talk on the topic

**” A class of Hausdorff – Berezin operators on**

**the unit disc”**

**Abstract.**It is introduce and study the class of Hausdorff-Berezin operators on the unit disc in the Lebesgue p-spaces with Haar measure. We discuss certain algebraic properties of such operators, and also give sufficient, and, in some cases necessary boundedness conditions for such operators. [ Joint work with Profs. K.Zhu and S.Samko ].
