Two-weight T1 theorem for fractional Riesz transforms: one measure supported on a curve
Ji Li, Chun-Yen Shen, Eric Sawyer +1
Let , and let and be locally finite positive Borel measures on , possibly with common point masses. Suppose that one measure is supported on a compact regul…
An Algebraic Approach to Constrained K-means Clustering
Hiroki Oohori, Kentaro Fukushima, Michio Yamamoto
Clustering is typically performed using only object features, although additional information about relationships between objects may be available and can be incorporated through c…
Commutators with two matrix weights
Ji Li, Chong-Wei Liang, Chun-Yen Shen +1
Let be matrix weights, , and let be a matrix-valued function. For Calderón--Zygmund operators with scalar standard kernels, we characterize…
Martingale Transforms and Compensated Bellman Estimates for Dunkl Riesz Transforms
Francesco D'Emilio, Brett D. Wick
We develop a martingale-transform framework for Dunkl harmonic analysis and apply it to prove estimates for the Dunkl Riesz transforms using the martingale decomposition of t…
The Corona Problem for Slice Holomorphic Functions via the Matrix Corona Problem
Fabrizio Colombo, Elodie Pozzi, Irene Sabadini +1
In this paper we prove the Corona theorem for slice hyperholomorphic functions in a general way that applies to functions with values in a Clifford algebra for any $n…
Two-weight inequalities for the Dunkl--Poisson integrals
Qingdong Guo, Ji Li, Brett D. Wick +1
We prove an two-weight testing theorem for the Dunkl--Poisson semigroup. The difficulty is geometric. The Dunkl orbit distance has several reflected diagonals, so a single or…
