Russian Academy of Sciences (RAS) and Moscow State University (MSU)



(Moscow, August 24 - 28, 2004)

of Ljudmila Vsevolodovna Keldysh
(March 12, 1904 - February 16, 1976)

Scopes and Themes

The conference will cover the areas of L.V. Keldysh’s scientific interests as well as some modern development in geometry and topology. There will be four sections:
  • Geometric Topology (A.V. Chernavsky , E.V. Shchepin)
  • Set Theory (V.V. Fedorchouk, V.G. Kanovei, V.A. Lyubetsky)
  • Topology of Low Dimensions (S.V. Matveev, I.A. Dynnikov)
  • Combinatorial geometry and algebraic topology (V.M. Buchstaber)

Ljudmila Vsevolodovna Keldysh was an eminent mathematician. She first worked in Descriptive Set Theory (being a member of the celebrated Lusitania - a mathematiciancommunity grouped around N.N. Lusin), and then, from the 50's, in the domain of Geometric Topology.
Her main result in Descriptive Theory consists in the full analysis of the Borel sets, including the construction of arithmetic examples for all effectively given transfinites.
In Topology, she is the author of the well known examples of open null-dimensional mapping of the Menger curve onto cubes and open monotone mappings of cubes onto cubes of higher dimension. This work stimulated many further studies.
In the last period of her life L.V. Keldysh conducted a seminar inGeometric Topology, which has markedly influenced modern state of the field.
