On questions which are connected with Talagrand problem

Abstract: We prove the following results. 1. If $X$ is a $\alpha$-favourable space, $Y$ is a regular space, in which every separable closed set is compact, and $f:X\times Y\to\mathbb R$ is a separately continuous everywhere jointly discontinuous function, then there exists a subspace $Y_0\subseteq Y$ which is homeomorphic to $\beta\mathbb N$. 2. There exist a $\alpha$-favourable space $X$, a dense in $\beta\mathbb N\setminus\mathbb N$ countably compact space $Y$ and a separately continuous everywhere jointly discontinuous function $f:X\times Y\to\mathbb R$. Besides, it was obtained some conditions equivalent to the fact that the space $C_p(\beta\mathbb N\setminus\mathbb N,{0,1})$ of all continuous functions $x:\beta\mathbb N\setminus\mathbb N\to{0,1}$ with the topology of point-wise convergence is a Baire space.
