Convexity of the Petrović-Type Functionals

and Applied Analysis 3 Remark 1.5. If f x /x is increasing on I and 1.6 holds, then the Petrović-type functional P1 is nonnegative, that is, inequality 1.4 is valid. Conversely, if f x /x is increasing on I and conditions as in 1.7 are fulfilled, then relation 1.5 holds. In order to define another Petrović-type functional, we cite the following Petrović-type inequality involving a convex functi...

Hardy Type Inequalities via Convexity - the Journey so Far

It is nowadays well-known that Hardy’s inequality (like many other inequalities) follows directly from Jensen’s inequality. Most of the development of Hardy type inequalities has not used this simple fact, which obviously was unknown by Hardy himself and many others. Here we report on some results obtained in this way mostly after 2002 by mainly using this fundamental idea.

On Boas-type Problem

R.P. Boas has found necessary and sufficient conditions of belonging of function to Lipschitz class. From his findings it turned out, that the conditions on sine and cosine coefficients for belonging of function to Lip α (0 < α < 1) are the same, but for Lip 1 are different. Later his results were generalized by many authors in the viewpoint of generalization of condition on the majorant of mod...

Hardy type derivations on fields of exponential logarithmic series

We consider the valued field K := R((Γ)) of formal series (with real coefficients and monomials in a totally ordered multiplicative group Γ ). We investigate how to endow K with a logarithm l, which satisfies some natural properties such as commuting with infinite products of monomials. In [KM10], we studied derivations on K. Here, we investigate compatibility conditions between the logarithm a...
