Pre-Dual of Fofana’s Spaces

Autor: Hans G. Feichtinger, Justin Feuto

Publikováno v: Mathematics, Vol 7, Iss 6, p 528 (2019)

The purpose of this paper is to characterize the pre-dual of the spaces introduced by I. Fofana on the basis of Wiener amalgam spaces. These spaces have a specific dilation behaviour similar to the spaces L α ( R d ) . The characterization of the pr

A weighted inequality for potential type operators

Autor: Aïssata Adama, Ibrahim Fofana, Justin Feuto

Publikováno v: Advances in Pure and Applied Mathematics. 10:413-426

We establish a weighted inequality for fractional maximal and convolution type operators, between weak Lebesgue spaces and Wiener amalgam type spaces on $ \mathbb R $ endowed with a measure which needs not to be doubling.

We give a $\operatorname{div}$-$\operatorname{curl}$ type lemma for the wedge product of closed differential forms on ${\mathbb R}^n$ when they have coefficients respectively in a Hardy space and $L^\infty$ or $\mathit{BMO}$. In this latter case, the

A generalization of the Carleson lemma and weighted norm inequalities for the maximal functions in the Orlicz setting

Publikováno v: Journal of Mathematical Analysis and Applications. 491:124248

In this note we introduce the notion of Φ-Carleson sequence for Φ a convex growth function and provide an equivalent characterization that is an extension of the off-diagonal Carleson embedding lemma. We apply this result to obtain Sawyer-type char
