Феноменологическая модель, объясняющая происхождение несоответствия в измерениях постоянной Хаббла One of the problem revealed recently in cosmology is a so-called Hubble tension (HT), which is the difference between values of the present Hubble constant, measured by observation of the universe at redshift z < 1, and by observations of a distant universe with CMB fluctuations originated at z ∼ 1100. In this paper we suggest, that this discrepancy may be explained by deviation of the cosmological expansion from a simple Friedman model of a flat dusty universe during the period after recombination at z < 1100, due to action of additional small component of a dark energy of a different origin.. We suppose, that a dark matter (DM) has a common origin with a small component of a dark energy (DEV). DE presently may have two components, one of which is the Einstein constant \Lambda, and another, smaller component DEV (A_v ) comes from the remnants of a scalar fields responsible for inflation. Due to common origin and interconnections the ratio between DEV and DM densities is supposed to remain constant during, at least, the time after recombination, when we may have \rho_{DEV} = \alpha\rho_{DM}. This part of the dark energy in not connected with the cosmological constant \Lambda, but is defined by existence of scalar fields with a variable density. Taking into account the influence of DEV on the universe expansion We find the value of \alpha ~100 which should remove the HT problem. http://master.sai.msu.ru/ru/ura2020/program
