Boundedness of Marcinkiewicz Integrals on RBMO Spaces over Nonhomogeneous Metric Measure Spaces
Let X,d,μ be a metric measures space satisfying the upper doubling conditions and the geometrically doubling conditions in the sense of Hytönen. Under the assumption that the dominating function satisfies the weak reverse doubling condition, the authors ...

Endpoint multiplier theorems of Marcinkiewicz type
We establish sharp (H^1, L^{1,q}) and local (L \log^r L, L^{1,q}) mapping properties for rough one-dimensional multipliers. In particular, we show that the multipliers in the Marcinkiewicz multiplier theorem map H^1 to L^{1,\infty} and L \log^{1/2} L to ...

On some properties of generalized Marcinkiewicz spaces [PDF]
Let \((X_0,X_1)\) be a couple of interpolation of Banach spaces, and, for \(t>0\), and \(x\in X_0+X_1\): \[ K(t,x)= \inf\{\|x_0\|_{X_0}+t \|x_1\|_{X_1}, \;x=x_0+x_1\} . \] For any quasiconcave function \(\varphi: (0,\infty)\to (0,\infty)\), the generalized Marcinkiewicz space \(M_\varphi=M_\varphi(X_0,X_1)\) is the set of \(x\in X_0+X_1\) for which \[ \

Marcinkiewicz integrals with variable kernels on Hardy and weak Hardy spaces
In this article, we consider the Marcinkiewicz integrals with variable kernels defined by μΩ(f)(x)=(∫0∞|∫|x−y|≤tΩ(x,x−y)|x−y|n−1f(y)dy|2dtt3)1/2, where Ω(x,z)∈L∞(ℝn)×Lq(Sn−1) for q > 1.

Fixed point properties for a degenerate Lorentz–Marcinkiewicz space
Fixed point properties of a renorming of \((\ell^1, \|\cdot\|_1)\) and a predual of the renormed space are investigated. If \(x = (x_n) \in \ell^1\), \(|||x||| = \|x\|_1 + \|x\|_\infty\) defines a norm on \(\ell^1\) equivalent to the canonical norm.
