Aleksandr Aleksandrov (mathematician)

Aleksandr Aleksandrov (1912–2001) was a prominent Russian mathematician known for his significant contributions to various areas of mathematics, particularly in topology and geometry. He is most noted for his work in the field of general topology and for his contributions to the theory of convex polyhedra. One of his key achievements was the development of the concept of Alexandrov spaces, which generalizes some properties of geometric spaces, particularly in relation to curvature and metric spaces.
