On a conjecture of Nikiforov involving a spectral radius condition for a graph to contain all trees
Xiangxiang Liu, Hajo Broersma, Ligong Wang
We partly confirm a Brualdi-Solheid-Turán type conjecture due to Nikiforov, which is a spectral radius analogue of the well-known Erdős-Sós Conjecture that any tree of order is…

Spectral radius conditions for the existence of all subtrees of diameter at most four
Xiangxiang Liu, Hajo Broersma, Ligong Wang
Let denote the spectral radius of a graph . We partly confirm a conjecture due to Nikiforov, which is a spectral radius analogue of the well-known Erdős-Sós Conjecture th…
