Banach algebra of the Fourier multipliers on weighted Banach function spaces
Let MX,w(ℝ) denote the algebra of the Fourier multipliers on a separable weighted Banach function space X(ℝ,w).We prove that if the Cauchy singular integral operator S is bounded on X(ℝ, w), thenMX,w(ℝ) is continuously embedded into L∞(ℝ).

A direct proof of the weighted Pólya–Knopp inequality following Carleson’s method
The aim of the paper is to provide a direct proof of the weighted Pólya–Knopp inequality. This inequality (which is a limiting case of the Ariño–Muckenhoupt inequalities), involving non-increasing functions, was initially established by Sbordone–Wik, who

In this article we consider quasi-linear second-order elliptic equations of divergence structure with Makenhaupt weight that degenerates over a small part of the domain. We show that the classical Harnack's inequality does not hold in this case, and

Muckenhoupt weights and Lindelöf theorem for harmonic mappings
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 Lindelöf to the class of quasiconformal (q.c.) harmonic mappings by proving the following assertion.

An extension of the Muckenhoupt–Wheeden theorem to generalized weighted Morrey spaces
Abstract In this paper, we find the condition on a function ω and a weight v which ensures the equivalency of norms of the Riesz potential and the fractional maximal function in generalized weighted Morrey spaces

Parabolic Muckenhoupt weights in the Euclidean space
The author introduces the parabolic analogue to Muckenhoupt's \(A_p\) weights. Given a cube \(Q=\prod_{i=1}^n [a_i, a_i+h]\) and \(r>0\), the author denotes by \[ Q^{+,r}= \prod_{i=1}^{n-1} \big[a_i,a_i+h\big]\times \big[a_n+rh,a_n+(r+1)h\big] \] the forward in time \(r\)-translation of the cube. Similarly, the backward \(r\)-translation is denoted by \
