Muckenhoupt weights and Lindel\"of theorem for harmonic mappings [PDF]

, 2014
We extend the result of Lavrentiev which asserts that the harmonic measure and the arc-length measure are $A_\infty$ equivalent in a chord-arc Jordan domain. By using this result we extend the classical result of Lindel\"of to the class of quasiconformal

Musielak-Orlicz-Hardy Spaces Associated with Operators Satisfying Reinforced Off-Diagonal Estimates

Analysis and Geometry in Metric Spaces, 2013
Let X be a metric space with doubling measure and L a one-to-one operator of type ω having a bounded H∞ -functional calculus in L2(X) satisfying the reinforced (pL; qL) off-diagonal estimates on balls, where pL ∊ [1; 2) and qL ∊ (2;∞]. Let φ : X × [0;∞) →

A note on weights: Pasting weights and changing variables

Journal of Inequalities and Applications, 2002
For two weights , on , we show that (the Muckenhoupt class of weights) if and only if and , under the assumption that for every . We also prove a rather general result on pasting weights on that satisfy the condition.

Calderón weights as muckenhoupt weights

, 2013
The Calder on operator S is the sum of the the Hardy averaging operator and its adjoint. The weights w for which S is bounded on L p (w) are the Calder on weights of the class Cp.

Local W^{1,p}-regularity estimates for weak solutions of parabolic equations with singular divergence-free drifts

Electronic Journal of Differential Equations, 2017
We study weighted Sobolev regularity of weak solutions of non-homogeneous parabolic equations with singular divergence-free drifts. Assuming that the drifts satisfy some mild regularity conditions, we establish local weighted $L^p$-estimates for the

Best trigonometric approximation and modulus of smoothness of functions in weighted grand Lebesgue spaces

Қарағанды университетінің хабаршысы. Математика сериясы, 2019
In this work, first of all, Lpw),Ө (T) weighted grand Lebesgue spaces and Muckenhoupt weights is defined. The information about properties of these spaces is given. Let Tn be the trigonometric polynomial of best approximation.
