| Abstract :
The investigation of quantum correction
to the action of gravity is a
complicated problem, which is not
completely resolved yet. At the same
time, a set of simple assumptions such
as covariance arguments, enable us to
write down a general form of the quantum
vacuum contributions up to a single free
coefficient. It is interesting that the
theory with such corrections is capable
to explain the rotation curves in
different types of galaxies without
usual LCDM part. This fact gives some
serious background to attempts to create
an alternative cosmic concordance model
with much smaller amount of WDM and
dominating cosmological constant. The
study of gravitational lensing in this
model looks very promising and
interesting task. |
