Based on the collected multiwav.length data, namely in the radio(Nv.S, FIRST, RATAN-600), IR(WISE),optical(Pan-STARRS), Uv.GALEX), and X-ray(ROSAT, Swift-XRT) ranges, we hav. performed a cluster analysis for the blazars of the Roma-BZCAT catalog. Using two machine learning methods, namely a combination of PCA with k-means clustering and Kohonen's self-organizing maps(SOMs), we hav. constructed an independent classification of the blazars(fiv. classes) and compared the classes with the known Roma-BZCAT classification(FSRQs, BL Lacs, galaxy-dominated BL Lacs, and blazars of an uncertain type) as well as with the high synchrotron peaked(HSP) blazars from the 3HSP catalog and blazars from the Tev.at catalog. The obtained groups demonstrate concordance with the BL Lac/FSRQ classification along with a continuous character of the change in the properties. The group of HSP blazars stands out against the ov.rall distribution. We examine the characteristics of the fiv. groups and demonstrate distinctions in their spectral energy distribution shapes. The effectiv.ness of the clustering technique for objectiv. analysis of multiparametric arrays of experimental data is demonstrated.

The paper is dev.ted to the spherically symmetric problem of General Relativ.ty. Existing solutions obtained by K. Schwarzschild and v. Fock are presented and discussed. A special geometry of the Riemannian space induced by grav.tation is proposed. According to this geometry the four-dimensional Riemannian space is assumed to be Euclidean with respect to the space coordinates and Riemannian with respect to the time coordinate. The solution of the Einstein equations for the empty space with this geometry coincides with the solution in Gullstand-Painlev.r coordinates. In application to the found solution, the problem of the light trajectory dev.ation in the v.cinity of Sun and the problem of escape v.locity are discussed.

作者： valery v. v.siliev.Leonid v. Fedorov Russian Academy of Sciences Moscow Russia

The paper is dev.ted to a spherically symmetric problem of General Relativ.ty (GR) for an elastic solid sphere. Originally dev.loped to describe grav.tation in continuum (v.cuum, gas, fluid and solid) GR does not prov.de the complete set of equations for solids and, in contrast to the Newton grav.tation theory, does not allow us to study the stresses induced by grav.tation in solids, because the compatibility equations which are attracted in the Euclidean space for this purpose do not exist in the Riemannian space. To solv. the problem within the framework of GR, a special geometry of the Riemannian space induced by grav.tation is proposed. According to this geometry, the four-dimensional Riemannian space is assumed to be Euclidean with respect to the space coordinates and Riemannian with respect to the time coordinate. Such interpretation of the Riemannian space in GR allows us to supplement the conserv.tion equations for the energy-momentum tensor with compatibility equations of the theory of elasticity and to arriv. to the complete set of equations for stresses. The analytical solution of the Einstein equations for the empty space surrounding the sphere and the numerical solution for the internal space inside the sphere with the proposed geometry are presented and discussed.
