Noncommutative weak type estimates for Calderón-Zygmund operators with a class of -integral conditions
Xudong Lai, Lingxin Xu
We construct a slightly new noncommutative Calderón-Zygmund decomposition by further splitting the bad function. Using this tool, we prove the weak type (1,1) boundedness of noncom…
Spurion Analysis of Non-Invertible Selection Rules: Low-Order versus All-Order Zeros
Motoo Suzuki, Ling-Xiao Xu
Motivated by recent progress in the spurion analysis of non-invertible selection rules (NISRs) arising from near-group fusion algebras, we further generalize the framework to a cla…
Spurion Analysis for Non-Invertible Selection Rules from Near-Group Fusions
Motoo Suzuki, Ling-Xiao Xu, Hao Y. Zhang
We generalize the framework of spurion analysis to a class of selection rules arising from non-invertible fusion algebras in perturbation theory. As a first step toward systematic…
Staggered Fermions with Chiral Anomaly Cancellation
Ling-Xiao Xu
We investigate the implications of the quantized vectorial and axial charges in the lattice Hamiltonian of multi-flavor staggered fermions in dimensions. These lattice char…
