Evaluation of Some Sums Involving Powers of Harmonic Numbers
Ce Xu, Xixi Zhang, Jianqiang Zhao
In this note, we extend the definition of multiple harmonic sums and apply their stuffle relations to obtain explicit evaluations of the sums $R_n(p,t)=\sum\nolimits_{m=0}^n m^p H_…
Some Evaluations of Parametric Euler Type Sums of Harmonic Numbers
Junjie Quan, Ce Xu, Xixi Zhang
We establish some identities of Euler related sums. By using these identities, we discuss the closed form representations of sums of harmonic numbers and reciprocal parametric bino…
On the spectral moment of graphs with given clique number
Shuna Hu, Shuchao Li, Xixi Zhang
Let be the set of all -vertex connected graphs with clique number \,(. For -vertex connected graphs with given clique number, lexicogra…
Edge-grafting theorems on permanents of the Laplacian matrices of graphs and their applications
Shuchao Li, Yan Li
The trees, respectively unicyclic graphs, on vertices with the smallest Laplacian permanent are studied. In this paper, by edge-grafting transformations, the -vertex trees o…
