  An International Workshop dedicated to the anniversary of the Polyakov's
String (of course today there is no need to remind the meaning and the role of
this theory) was held in Chernogolovka in June 2005. Apart from the 25-th
anniversary of the first appearance of the Polyakov's String theory, this
conference, to our mind, might be also thought of as a 35 years from the
discovery of the Conformal Invariance, 30 years of the Monopole and the
Instantons and, finally, as the 20-th anniversary of the CFT. A case of
mysterious coincidence, this year is also a jubilee of Sasha himself, whose
contribution to the Theoretical Physics of 20-th century is far from being
exhausted by the achievements listed above.
