On 1^st March 2023 at 10:00 at the seminar of the Institute of Mathematics and Mechanics a senior researcher of the department “Function Theory”, cand. ph.-m. s., associate professor, Niyazi Aladdin oglu Ilyasov will speak with presentation entitled “On various properties of periodic summable functions with only one condition on modulus of continuity of the second order”.

We find exact descending orders for a number of quantities, which characterize various properties of 2π- periodic summable functions from the class with a given majorant of a modulus of continuity of the second order. It is proved that all these quantities have the same descending order (under a condition on majorant), which is realized by one extremal function.
