His current research findings presented in the lecture show that certain classes of 3-dimensional space-times can exist only as solutions of the non-vacuum Einstein equations - ie in the presence of matter. Furthermore, a classification of the corresponding homogeneous solutions was presented and the geometric properties of these spacetimes were analyzed. The results provide an important contribution to the understanding of 3-dimensional theory of gravity.
