The paper of the senior research ass. of the department of functions theory, doctor of physico-mathematical sciences, professor Alik Najafov and PhD in Mathematics Rana Karbalayeva was published. The article was published in the journal “Georgian Mathematical Journal” with a 0.482 Impact Factor, referenced by the Clarivate Analytics international database.

In the article titled “The Theorems of the Besov-Morri Fields with Multiple Variables”, the differential and differential-difference properties of the functions of the Besov-Morri spaces with multi variable spaces are studied. It has also been proven that the generalized mixed derivative of the functions of these spaces is included in the Hölder class.

Depending on Besov-Morrey type spaces with multiple variables, the known Besov-Morrey spaces, in the intermediate values the new Besov-Morrey type spaces were obtained.
