Nagy type inequalities in metric measure spaces and some applications
Vladyslav Babenko, Vira Babenko, Oleg Kovalenko +1
We obtain a sharp Nagy type inequality in a metric space with measure that estimates the uniform norm of a function using its -- norm determined by a…

On Landau -- Kolmogorov type inequalities for charges and their applications
Vladyslav Babenko, Vira Babenko, Oleg Kovalenko +1
In this article we prove sharp Landau--Kolmogorov type inequalities on a class of charges defined on Lebesgue measurable subsets of a cone in , , that are ab…
