On the exact constants in Hardy – Littlewood inequalities

Motornyi V. P.

↓ Abstract

Ukr. Mat. Zh. - 2017. - 69, № 12. - pp. 1625-1632

We obtain the exact constants for the Hardy – Littlewood inequalities.

Weighted limit solution of a nonlinear differential equation at a singular point and its property

Dzhumabaev D. S., Uteshova R. E.

↓ Abstract

Ukr. Mat. Zh. - 2017. - 69, № 12. - pp. 1717-1722

On a finite interval, we consider a system of nonlinear ordinary differential equations with a singularity at the left endpoint of the interval. The definition of weighted limit solution is introduced and its attracting property is established.

Inverse problem for the heat equation in a rectangular domain

Ivanchov N. I., Kinash N. Ye.

↓ Abstract

Ukr. Mat. Zh. - 2017. - 69, № 12. - pp. 1605-1614

We establish conditions for the existence and uniqueness of a smooth solution to the inverse problem for the two-dimensional heat equation with unknown leading coefficient depending on time and the space variable.
