The phenomenon of origin of Polish mathematical school (before 1939)

We shall describe briefly a development of mathematics in two parts (of Russia and of Austria-Hungary) of Poland at the turn of the century XIX-XX. A choice of new directions of mathematics in Poland before (1915-1918) and after (1918-1926) independence restoration until May 1926 coup. The progress in mathematics in the time of Piłsudski (1926-1935). The progress in mathematics in 1936-1939. Simultaneously to historical picture new mathematical schools will be describe: in set-theoretic topology, in mathematical logic, in functional analysis and theory of approximation, in probability theory and mathematical statistics, with biographies of eminent scientists of this schools (H.

Besides literature the lecturer uses private sources to wit talks with academicians K.Kuratowski, A. Pelchynski, Ch. Bessaga in 1979-1980, and sources from conferences on historia of mathematics in Poland author took part in 1990-th and 2000-th.
