Extrapolation for bilinear compact operators in the variable exponent setting

Spyridon Kakaroumpas, Stefanos Lappas

We establish extrapolation of compactness for bilinear operators in the scale of weighted variable exponent Lebesgue spaces. First, we prove an abstract principle relying on the Co…

Sharp bilinear estimates for maximal singular integrals with kernels in weighted $L^{q}$ spaces

Stefanos Lappas, Bae Jun Park

In this paper, we study the boundedness properties of the (dyadic) maximal bilinear operator associated with rough homogeneous kernels on $R$ . We establish sharp $L^{p_1}(…

Factorizations for variable exponent Muckenhoupt weights

Stefanos Lappas, Tuomas Oikari

Given two variable exponent Muckenhoupt weights $w \in A_{p (\cdot)}$ and $w_{1} \in A_{p_{1} (\cdot)}$ , we prove that for all small enough $θ > 0,$ there holds that $w_0…
