All pupils of A.D.Alexandrov which had the scientific degrees Doctor of Science

## Leningrad and Interior geometry of convex surfaces

Alexandrod constructs the interior and geometry of convex surfaces and
and the theory of manifolds of bounded curvature (in the sense of
A.D.Alexandrov,
or the Alexandrov spaces) in his Leningrad life period.
The Leningrad's pupils are given on the photo below

**Novosibirsk and Chronogeometry**

A.D. Alexanrov arrived in Novosibirsk in 1964. Here he began to investigate
the mathematical theory of space-time. A new research area was created,
called Chronogeometry. A.D. Alexandrov and his students (see a photo below)
got many interesting results. There was a special seminar "Chronogeometry"(Russian,
koi-8).
