He planned, in collaboration with the Swiss mathematician H.Hopf, to produce a definitive multi-volume topological treatise. Only the first volume, Topologie 1 (1935), was published. It was nonetheless extremely influential and did much to encourage the development of the Moscow school of topology. Aleksandrov’s own work, initially in set-theoretic topology, later moved into the field of algebratic topology.
During his life, he wrote about three hundred papers, making important contributions to set theory and topology.
Aleksandrov, Pavel Sergeevich
