For the first time, characteristics of radiation were estimated for the extended structure surrounding the accretion disc of the Q2237+0305 quasar, namely, the upper limit for the energy contribution of the structure in different regions of the optical spectral range. A chapter "Gravitational lensing as a key to solving the dark matter problem" is prepared for publication in the joint monograph on the Program "Cosmicrophysics", which contains the key results obtained during 2009-2011. Numerical simulation of the high amplification events are fulfilled for various source models in two cases: with the appreciable dark matter content near the line of sight and for the finite-size microlens. Solutions of the problem of lensing by a complex lens for an arbitrary location of a microlens along the source-macrolens-observer path. Isophots for macroimages are built and the amplification rate for the complex lens was calculated.
