Abstract: Renat Abugaliev. Let $X$ be a rational surface and $G$ acts on $X$. I will talk about the first cohomology group of $G$ with coefficients in $\mathrm{Pic}\, X$. Smail Temirlan. In this work we will consider some results connected with classification of finite subgroups of automorphism group of del Pezzo surfaces of degree one and two.
