On the Jensen-Steffensen inequality for generalized convex functions
Jensen–Steffensen type inequalities for P -convex functions and functions with nondecreasing increments are presented. The obtained results are used to prove a generalization of Čebyšev’s inequality and several variants of Hölder’s inequality with weights satisfying the conditions as in the Jensen–Steffensen inequality. A few well-known inequalities for quasi-arithmetic means are generalized.
متن کاملAsymptotic behavior of alternative Jensen and Jensen type functional equations
In 1941 D.H. Hyers solved the well-known Ulam stability problem for linear mappings. In 1951 D.G. Bourgin was the second author to treat the Ulam problem for additive mappings. In 1982–2005 we established the Hyers–Ulam stability for the Ulam problem of linear and nonlinear mappings. In 1998 S.-M. Jung and in 2002–2005 the authors of this paper investigated the Hyers–Ulam stability of additive ...
متن کاملThe Jensen Covering Property
The Jensen covering lemma says that either L has a club class of indiscernibles, or else, for every uncountable set A of ordinals, there is a set B ∈ L with A ⊆ B and card(B) = card(A). One might hope to extend Jensen’s covering lemma to richer weasels, that is, to inner models of the form L[ ~ E] where ~ E is a coherent sequence of extenders of the kind studied in Mitchell-Steel [MiSt]. The pa...
متن کاملTotal Jensen divergences: Definition, Properties and k-Means++ Clustering
We present a novel class of divergences induced by a smooth convex function called total Jensendivergences. Those total Jensen divergences are invariant by construction to rotations, a feature yieldingregularization of ordinary Jensen divergences by a conformal factor. We analyze the relationships be-tween this novel class of total Jensen divergences and the recently introduced tota...
متن کاملOn the stability of multi-m-Jensen mappings
In this article, we introduce the multi-$m$-Jensen mappings and characterize them as a single equation. Using a fixed point theorem, we study the generalized Hyers-Ulam stability for such mappings. As a consequence, we show that every multi-$m$-Jensen mappings (under some conditions) is hyperstable.
