The planar Turan number of double star S_(3,5)
Dandan Liu, Shoujun Xu
Given a graph H and a positive integer n, the planar Turan number of H, denoted by exp(n, H), is the maximum number of edges in an n-vertex H-free planar graph.D.Ghosh, et al.initi…

The Turan number of the balanced double star S_{n-1,n-1} in the hypercube Q_n
Shoujun Xu, Dandan Liu
The n-dimensional hypercube Q_n is a graph with vertex set {0,1}^n such that there is an edge between two vertices if and only if they differ in exactly one coordinate. Let H be a…
