Optimal Sparse Bounds and Commutator Characterizations Without Doubling
Francesco D'Emilio, Yongxi Lin, Nathan A. Wagner +1
We examine dyadic paraproducts and commutators in the non-homogeneous setting, where the underlying Borel measure is not assumed to be doubling. We first establish a pointwise…

Matrix Weighted Estimates in the Nonhomogeneous Setting
Fernando Benito-de la Cigoña, Tainara Borges, Francesco D'Emilio +2
We establish a modified pointwise convex body domination for vector-valued Haar shifts in the nonhomogeneous setting, strengthening and extending the scalar case developed in arXiv…
