We deal with some functional inequalities which are motivated by the following relation between the geometric mean G, the logarithmic mean L and the arithmetic mean A: $$ G^{\frac{2} {3}} \cdot A^{\frac{1} {3}} \leqq L \leqq \frac{2} {3}G + \frac{1} {3}A. $$ 相似文献

In a recent paper (Studia Math. 138 (2000) 285-291) we proved pointwise estimates relating some classical maximal and singular integral operators. Here we show that, in a sense, there are more flexible inequalities which not only imply the previously known results but also give something new. In particular, they hold for the multilinear Calderón-Zygmund operators. This result gives a new approach to a recent work by Grafakos and Torres, and unifies some classical inequalities by Cotlar and Coifman and Fefferman. 相似文献

We prove the equivalence between analogs of the Paley and Nikol’skii inequalities for any orthonormal system of functions
and for almost periodic polynomials with arbitrary spectrum.

In the present paper we establish some new inequalities similar to extensions of Hilbert’s double-series inequality and give
also their integral analogues. Our results provide some new estimates to these types of inequalities. 相似文献

Some new discrete inequalities involving higher order differences have been obtained here. These inequalities can be used in the analysis of a class of summary difference equations as handy tools. Some applications are also given. 相似文献

Summary A class of parabolic variational inequalities is investigated, where: the unilateral constraints concern the time derivative of the unknown function; degeneracies or singularities with respect to the time variable are considered. Some general abstract existence and uniqueness results are proved, in the natural framework of suitable weighted spaces.

Sunto Si studia una classe di disequazioni variazionali paraboliche, dove: i vincoli unilaterali riguardano la derivata rispetto al tempo delta funzione incognita; vengono considerate singolarità e degenerazioni rispetto alla variabile temporale. Si dimostrano alcuni risultati generali di esistenza ed unicità, nell'ambito naturale di opportuni spazi con peso.

Given a weight ω, we consider the space which coincides with when ω∈Ap. Sharp weighted norm inequalities on for the Calderón-Zygmund and Littlewood-Paley operators are obtained in terms of the Ap characteristic of ω for any 1<p<∞. 相似文献
