**General Description **

As it is written above on the main page, my interests in general concern number theory and related topics, such as algebraic and arithmetic geometry. The main objects I am working with are global fields in positive characteristic. The most useful tool in my research is the class-field theory. In practice, I usually use the Magma computational algebra system.

In my bachelor thesis I investigated some asymptotic properties of distribution of curves and abelian varieties over finite fields with fixed restriction on the number of points on such curves on the ground field. In my master thesis I constructed curves with many points over some small finite fields, by looking at all unramified abelian coverings of genus three curves. An extended version of this thesis is available on arXiv. Both my bachelor and master thesis were written under the scientific direction of professor Alexey Zykin. Also, I would like to mention professor Alexey Zaytsev, who was my co-advisor for the master thesis and actually suggested the topic.

My current research is about Anabelian properties of global fields. The main task of Grothendieck’s anabelian geometry is to find relations between an object X and its algebraic fundamental group π(X), provided this group is «sufficiently non-abelian». Suppose X=K is a number or a global function field. In this settings it is natural to consider π(X) as absolute Galois group G = Gal( K^{sep}/K). As pro-finite group the Galois-group G inherits a natural topology and hence it becomes a topological group. It is celebrated theorem due to Neukrich and Uchida which states that in this case isomorphism as topological groups of absolute Galois groups implies isomorphism of fields themselves. The same time, there exists an example which shows that it is not enough to consider abelianization of absolute Galois group to recover isomorphism class of K. In my research I am trying to find sufficient supplementary conditions on isomorphism of abelianizations, such that by using those conditions one indeed has implication about isomorphism of fields. A very related topic is arithmetical equivalence for global fields.
