On an Integral-type Operator From Mixed Norm Spaces to Bloch-type Spaces

假设n是正整数,g∈H(d)及φ是d上的解析自映射.本文主要研究了从混合模空间到blOCH型空间积分算子C_(φ,g)~n的有界性和紧性,其中积分算子C_(φ,g)~n定义为:(Cnφ,gf)(z)=∫(n)(φ(§))g(§)d§,z∈d,f∈H(d)Let n be a positive integer,g∈H(D) and φ be an analytic self-map of D.The boundedness and compactness of the integral operator C_(φ,g)~n,which is defined by(cnφ,gf)(z)=∫(n)(φ(§))g(§)d§,z∈D,f∈H(D) from the mixed norm spaces to the Bloch-type spaces are characterized.国家自然科学基金(No.11171080); 贵州省科学技术厅、贵州师范大学联合科技基金资助项目(黔科合J字LKS[2012]12号

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^

Measurement of integrated luminosity of data collected at 3.773 GeV by BESIII from 2021 to 2024

We present a measurement of the integrated luminosity e+e- of collision data collected by the BESIII detector at the BEPCII collider at a center-of-mass energy of Ecm = 3.773 GeV. The integrated luminosities of the datasets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 were determined to be 4.995±0.019 fb-1, 8.157±0.031 fb-1, and 4.191±0.016 fb-1, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects, and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements
