The main goal of the Workshop is to embrace recent results in developing Algebraic Graph Theory and its Applications. We are interested in algebraic, spectral and structural characterisation of highly regular graphs, investigating graphs defined on groups, constructing new graphs, codes and designs.

The workshop is organized by Mathematical Center in Akademgorodok in cooperation with the Sino-Russian Mathematics Center at Peking University in Beijing and the Three Gorges Mathematical Research Center at China Three Gorges University in Yichang.
