... The normal m 1 , c 1 indices and metallicities have been calculated for 2472 F-stars from the uvby and H fotometry. ... It is shown that the metallicity distribution of F6-G0 dwarfs is not a Gaussian one, but may be considered as a sum of two normal distributions. At the centre, the distribution shows a gap which subdivides all the stars into two metallicity groups. ... По данным uvby , H - фотометрии вычислены нормальные индексы m 1 , c 1 и определена металличность 2472 F-зыезд. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... The enumeration of singularities of differend kind is a classical subject of enumerative geometry. ... This problem was studied for last 30 years in the framework of intersection theory. ... The motivation for this formula came from topology, namely, from cobordism theory --- the field that looks rather far from algebraic geometry and intersection theory, perhaps, this was the reason why this formula were not observed before. ...
