Uniform supertrees with extremal spectral radii
《Frontiers of Mathematics in China》2020年第6期1211-1229,共19页Wen-Huan WANG Ling YUAN 
supported by the National Natural Science Foundation of China(Grant Nos.11871040,11001166).
A supertree is a connected and acyclic hypergraph.We investigate the supertrees with the extremal spectral radii among several kinds of r-uniform supertrees.First,by using the matching polynomials of supertrees,a new ...

Ordering uniform supertrees by their spectral radii被引量:4
《Frontiers of Mathematics in China》2017年第6期1393-1408,共16页Xiying YUAN Xuelian SI Li ZHANG 
This work was supported in part by the National Natural Science Foundation of China (Grant No. 11101263).
A supertree is a connected and acyclic hypergraph. For a hypergraph H, the maximal modulus of the eigenvalues of its adjacency tensor is called the spectral radius of H. By applying the operation of moving edges on hy...

Are phylogenies derived from family-level supertrees robust for studies on macroecologicai patterns along environmental gradients?被引量:4
《Journal of Systematics and Evolution》2016年第1期29-36,共8页Hong Qian Jian Zhang 
Ecologists frequently use a supertree method to generate phylogenies in ecological studies. However, the robustness of research results based on phylogenies generated with a supertree method has not been well evaluate...

Adding time-calibrated branch lengths to the Asteraceae supertree被引量:1
《Journal of Systematics and Evolution》2010年第4期271-278,共8页Rubén TORICES 
New inference techniques, such as supertrees, have improved the construction of large phylogenies, helping to reveal the tree of life. In addition, these large phylogenies have enhanced the study of other evolutionary...
