We analyze the local behavior of the Hausdorff centered measure for selfsimilar sets. If E is a self-similar set satisfying the open set condition, then Cs(E∩B
In this paper, we consider a Lorentz space with a mixed norm of periodic functions of many variables. We obtain the exact estimation of the best M-term approxim
In this short note, we show the behavior in Orlicz spaces of best approximationsby algebraic polynomials pairs on union of neighborhoods, when the measure ofthe
Let G?R2 be a regular anisotropic fractal. We discuss the problem of the negative spectrumfor the Schr ¨odinger operators associatedwith the formal expressi
In this paper we consider the class of Bazilevic functions for bi-univalent functions. For this we will estimate the coefficients a2 and a3using Caratheodory fu
In this work, using an analogue of Sadovskii’s fixed point result and several important inequalities we investigate and give new existence theorems for the non
