Bi-Jordan n-Derivations on Triangular Rings:Maximal Quotient Rings and Faithful Module
《Journal of Mathematical Research with Applications》2024年第5期596-616,共21页Xinfeng LIANG Lingling ZHAO 
Supported by the Open Research Fund of Hubei Key Laboratory of Mathematical Sciences(Central China Normal University);the Natural Science Foundation of Anhui Province(Grant No.2008085QA01);the University Natural Science Research Project of Anhui Province(Grant No.KJ2019A0107)。
In this paper,we mainly study the structure of bi-Jordan n-derivations in triangular rings under conditions of maximal quotient rings and faithful bimodules,respectively.It is shown that every bi-Jordan n-derivation c...

Extremal First Leap Zagreb Index of k-Generalized Quasi-Trees
《Journal of Mathematical Research with Applications》2022年第3期221-229,共9页Pei SUN Kai LIU 
Supported by the Foundation of Henan Department of Science and Technology(Grant No.182102310830);the Foundation of Henan University of Engineering(Grant No.D2016018);the Foundation of Henan Educational Committee(Grant Nos.20A110016;2020GGJS239)。
For a graph G,the first leap Zagreb index is defined as LM_(1)(G)=∑_(ν∈V(G))d_(2)(v/G)^(2),where d_(2)(v/G) is the 2-distance degree of a vertex v in G.Let QT^(k)(n) be the set of kgeneralized quasi-trees with n ve...

Duality for Multiobjective Bilevel Programming Problems with Extremal-Value Function被引量：1
《Journal of Mathematical Research with Applications》2015年第3期311-320,共10页Haijun WANG Ruifang ZHANG 
Supported by the National Natural Science Foundation of China(Grant No.11171250)
For a multiobjective bilevel programnfing problem （P） with an extremal-value function, its dual problem is constructed by using the Fenchel-Moreau conjugate of the functions involved. Under some convexity and monoto...
