In spite of existence o f a huge number of known cases where this procedure does work\, its validi ty and universality still remains mysterious in much extend.\n \nWe develo p a new tool based on the theory of KP hierarchy that allows one not only formally prove it in a unified way for a wide class of problems but also t o understand its true nature and the origin. These problems include enumer ation various kinds of Hurwitz numbers: ordinary ones\, orbifold\, double\ , monotone\, r-spin Hurwitz numbers\, as well as enumeration of (hyper) ma ps and extends much beyond. The talk is based on a joint work with B.Bychk ov\, P.Dunin-Barkowski\, S.Shadrin.\n LOCATION:https://researchseminars.org/talk/CGP-MP/16/ END:VEVENT END:VCALENDAR
