... Will there be interactive user accounts (telnet/SSH)? Will users be using it as a workstation or is it a server? ... The main difference in today's world between computers is usually not the hardware, or even the OS (Linux is Linux, NT Server and NT Workstation are close family, etc.), it is in what software packages are loaded (Apache, X, etc) and how users access the machine (interactively, at the console, and so forth). ...

REPORT ON PIERRE DELIGNE FELLOWSHIP, 2010 SERGEY OBLEZIN During 2010 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated to Lie groups of classical type. According to Givental the glN -Whittaker functions, being solutions to the quantum cohomology D-module QH (FlN ) of the complete flag variety FlN = GLN (C)/B , describe the corresponding equivariant Gromov-Witten invariants of FlN . ...

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ... DATA ANALYSIS We analyzed several CPO series obtained in IVS analysis centers by means of spectral and wavelet analysis. ...

My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms. I am particularly interested in the stability properties of accretion discs, the generation of MHD turbulence and associated angular momentum transport, disk - planet interactions and the origin and characteristics of jets and winds from accreting systems . ...
