Rough singular integrals associated to surfaces of revolution on product spaces
收藏 引用
Acta Mathematica Sinica,English Series 2025年
作者: Hussain AL-QASSEM Leslie CHENG Yibiao PAN Mathematics Program Department of Mathematics Statistics and Physics College of Arts and Sciences Qatar University department of Mathematics Bryn Mawr College department of Mathematics University of Pittsburgh
We study the Lpboundedness of singular integral operators along surfaces of revolution on product spaces. The Lpboundedness for these operators are obtained under very weak conditions on kernels. Our results are new a...

Extensions and Deformations of 3-Lie Algebras with Higher Derivations
收藏 引用
Journal of Mathematical Research with Applications 2025年 第1期 20-32页
作者: Shuangjian GUO School of Mathematics and statistics Guizhou University of Finance and Economics
In this paper, we call a tuple consisting of 3-Lie algebra and a higher derivation on it a 3-LieHDer pair. We introduce a cohomology theory of 3-LieHDer pairs. Next, we interpret the second cohomology group as the spa...
