International Conference
"GEOMETRY, TOPOLOGY, ALGEBRA and NUMBER THEORY, APPLICATIONS"
dedicated to the 120th anniversary of Boris Delone
16-20 August, 2010, Moscow

All talks will take place at the Steklov Mathematical Institute (Gubkina str. 8)

There will be 11 plenary talks and 1 online talk (morning sessions) and 4 sections: Geometry, Topology, Algebra and Number Theory, Applications (afternoon and evening sessions).

All plenary talks will take place in the Assembly Hall of the Steklov Mathematical Institute on the 9th floor.

Registration also will take place on the 9th floor of Steklov Institute.

Due to a large amount of submitted and accepted talks we will be unable to run all the program of the Conference in one stream. There will be a division into subsections during some days of the conference.

Please report of any inaccuracies to delone120@mi.ras.ru.
