## Abstract In a connected graph define the kβcenter as the set of vertices whose distance from any other vertex is at most __k.__ We say that a vertex set __S__ __d__βdominates __G__ if for every vertex x there is a y β __S__ whose distance from __x__ is at most __d__. Call a graph __P~t~__βfree
## Abstract For each vertex __u__ in a connected graph __H__, the __distance__ of __u__ is the sum of the distances from __u__ to each of the vertices __v__ of __H.__ A vertex of minimum distance in __H__ is called a __median__ vertex. It is shown that for any graph __G__ there exists a graph __H__
