A Generalization of σ-Permutability
《Communications in Mathematics and Statistics》2022年第3期565-579,共15页Zhigang Wang Jin Guo Inna N.Safonova Alexander N.Skiba 
supported by the NNSF of China(No.12171126,11961017);supported by Ministry of Education of the Republic of Belarus(grant 20211328);supported by the BRFFR(grant F20R-291).
Throughout this paper,all groups are finite and G always denotes a finite group;σis some partition of the set of all primes P.A group G is said to beσ-primary if G is aπ-group for someπ∈σ.Aπ-semiprojector of G[...

Congruence Pairs of Decomposable MS-Algebras
《Chinese Annals of Mathematics,Series B》2021年第4期561-574,共14页Sanaa El-ASSAR Abd El-Mohsen BADAWY 
supported by 2nd International Conference for Mathematics,Statistics and Information Technology(ICMSIT for short)that held in the Faculty of Science;Tanta University;Egypt,18-20December,2018。
In this paper,the authors first introduce the concept of congruence pairs on the class of decomposable MS-algebras generalizing that for principal MS-algebras(see[13]).They show that every congruence relationθon a de...

Finite Groups with Certain S-Permutable and GS-Maximal Subgroups
《Algebra Colloquium》2020年第4期661-668,共8页A.M.Elkholy M.H.Abd-Ellatif 
Let G be a finite group and H a subgroup of G.We say that H is S-permutable in G if H permutes with every Sylow subgroup of G.A group G is called a generalized smooth group(GS-group)if[G/L]is totally smooth for every ...

The Action on p-Groups and p-Supersolvability
《Algebra Colloquium》2017年第4期685-696,共12页Pengfei Bai Xiuyun Guo Boru Zhang 
The research was partially supported by the National Natural Science Foundation of China (11371237) and a grant of the First-Class Discipline of Universities in Shanghai.
Let a finite group A act on a finite p-group P with |P|〉 p^e, where e is an integer with e 〉 2. In this paper, we show that P is centralized by OP(A^Ap-1) if every non-maximal class p-group of order p^e in P is ...

LOOP GROUP ACTIONS AND THE RIBAUCOUR TRANSFORMATIONS FOR FLAT LAGRANGIAN SUBMANIFOLDS
《Chinese Annals of Mathematics,Series B》2005年第3期347-360,共14页XIAQIAOLING SHENYIBING 
Project supported by the National Natural Science Foundation of China (No.10271106)the Education Commission of Zhejiang Province of China (No.20030342).
The Ribaucour transformations for flat Lagrangian submanifolds in Cn and CPn via loop group actions are given. As a consequence, the authors obtain a family of new flat Lagrangian submanifolds from a given one via a p...
