Abstract
The recent measurements of circular velocity curves from weak lensing of the
isolated galaxies lead to a conclusion that the circular velocity curves remain
flat well beyond the virial radii of dark matter halos up to 1 Mpc. This is in
clear contradiction with the LCDM numerical simulations. We show that the
additional cosmic force originating from the geometry of the Universe beyond
the Friedmann model increases the circular velocities of the test galactic
bodies and avoids a decline of the standard LCDM velocity curves.
