    Abstract

    Let $D$ be a division ring with the center $F$. We say that $D$ is a {\em
    division ring of type $2$} if for every two elements $x, y\in D,$ the division
    subring $F(x, y)$ is a finite dimensional vector space over $F$. In this paper
    we investigate multiplicative subgroups in such a ring.
