The 6th Workshop on
«Algebraic Graph Theory and its Applications»
«Algebraic Graph Theory and its Applications»
March 21−25, 2022
The main goal is to embrace recent results in developing Algebraic Graph Theory and its Applications, in particular, we are interested in structural and spectral characterization of highly regular graphs, investigating graphs defined on groups, computing coherent closures of graphs, constructing new 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.
