Abstract
In a graph , we define a set of vertices to be a \emph{strong hub set} if for any two vertices in , we can find a path between them whose internal vertices are all in this set. We define the \emph{strong hub cover pebbling number} of , denoted by , to be the smallest such that for any initial configuration with pebbles on , we can make some pebbling moves (a pebbling move consists of removing two pebbles from a vertex and adding one pebble to another vertex adjacent to ) so that there is a strong hub set with every vertex in it having a pebble. We determine the strong hub cover pebbling numbers of paths, stars, and books.
