DESCRIPTION:title: Nonlinear differential equations and the geometric appro
 ach.\n\nAbstract: Nonlinear differential equations may have complicated si
 ngularities in the complex plane. Painleve equations are nonlinear second 
 order differential equations solutions of which have no movable critical p
 oints. They have a lot of nice properties. The quasi-Painleve equations ad
 mit algebraic branch points. The geometric approach to the Painleve equati
 ons was developed in the works of K. Okamoto\, H. Sakai and many others. I
 n thisvtalk I shall present some recent results using the geometric approa
 ch (including\, if time permits\, the general procedure of the reduction o
 f recurrence coefficients of semi-classical orthogonal polynomials to the 
 Painleve equations as an example of the solution of the so-called Painleve
  equivalence problem\, equations with the algebro-Painleve property\, equa
 tions with the quasi-Painleve property\, Lienard type equations and so on)
 . This talk is based on several published papers and preprints joint with 
 A. Dzhamay\, A. Ligeza\, A. Stokes and T. Kecker.\n\n \n\n \n\nTo get your
