       Physical conditions in luminous AGN.

The phenomenon of  active galactic nuclei   (AGN) has been  one of the
most intriguing subjects of astrophysical studies  in the past several
decades. Radio astronomy and very  long baseline interferometry (VLBI)
have played  a    crucial role  in  these  studies,   particularly  in
investigations  of  reltavistic outflows  (jets) commonly  observed in
luminous AGN. For the past 30 years,  radio interferometry has yielded
an impressive amount of information about the dynamics and composition
of  these  outflows, as  well  as about   the conditions in  the  most
compact, nuclear environment  in   the immediate vicinity   of central
engine of AGN.  The jets in  particularly well studied  sources 3C345,
3C273 and M87   have become the  testbeds for  numerous  numerical and
analytical  approaches  to modelling  the   relativistic outflows.   A
review of our recent studies of these three  objects will be presented
in this  talk. Particular  attention will  be paid  to the subject  of
internal structure observed in these jets and its implications for the
dynamical evolution of relativistic outflows.
