... Proof of the Dulac's conjecture: Polynomial vector field in the real plane has but a finite number of limit cycles. The proof of this short statement requires a book [44] published by AMS in 1991; it was the subject of the talk in the ICM-1990. ... The proof of the same conjecture given by Ecalle and based on the ideas of the four authors appeared in a book published in 1992. ...
