Graham's pebbling conjecture on Cartesian product of the middle graphs of even cycles

Zheng-Jiang Xia, Yong-Liang Pan, Jun-Ming Xu +1

A pebbling move on a graph consists of taking two pebbles off one vertex and placing one on an adjacent vertex. The pebbling number of a graph , denoted by , is the le…
