... I am interested in Fano varieties -- those whose some multiple of sheaf of higher holomorphic differentials embeds them to a pro jective space. Mirror conjectures state an existence of a so called dual Landau­Ginzburg model, that is an open smooth Calabi­Yau variety with non-trivial complex-valued function called potential. ... The pro ject has 3 main directions. ... Mirror Symmetry predicts duality between anticanonical sections of Fano variety and fibers of its dual Landau­Ginzburg model. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ...

Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...

In this paper we review our results on the properties and evolution of isolated neutron stars. We calculate space distributions of these objects for different assumptions about the kick velocity and show, that the distribution has a torus-like structure. We calculate the evolution of isolated neutron stars with and without magnetic field decay and give characteristic parameters for these cases with applications to ROSAT X-ray sources. ...
