Ivan DYNNIKOV (MSU, Moscow): On the complexity of braids . We define a measure of "complexity" of a braid which is natural with respect to both an algebraic and a geometric point of view. ... The geometrical complexity is some natural measure of the amount of distortion of the $n$ times punctured disk caused by a homeomorphism. Our main result is that the two notions of complexity are comparable. ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... In spite of the lack of rich clusters around us and the presence of large volumes completely free from galaxies (voids), the mean luminosity densities and the mean density of hydrogen mass in the Local Universe is one and a half - twice as high as their mean global values. However, the mean local density of the baryon mass is only 2% of the critical density of the Universe, which is twice as less as the baryon density from the nucleosynthesis data (local paradox of the baryon mass). ...
