چکیده
We classify all functions satisfying non-trivial families of PVIα equations. It turns out that, up to an Okamoto equivalence, there are exactly four families parameterized by affine planes or lines. Each affine space is generated by points of ”geometric origin”, associated either to deformations of elliptic surfaces with four singular fibers, or to deformations of three-sheeted covers of P1 with branching locus consisting of four points. ∗The first author was partially supported by a grant of the Faculty of Sciences of Sfax, Tunisia.

We classify all functions satisfying non-trivial families of PVIα equations. It turns out that all of these 23 solutions are of geometric origin: they are related to deformations of elliptic surfaces as proved earlier by Doran. Similarly, we prove that the same solutions can be obtained from deformations of three-sheeted covers of P1 with branching locus consisting of four points. e-mail: basse...
متن کاملPainlevé VI Equations with Algebraic Solutions and Family of Curves
In families of Painlevé VI differential equations having common algebraic solutions we classify all the members which come from geometry, i.e. the corresponding linear differential equations which are Picard-Fuchs associated to families of algebraic varieties. In our case, we have one family with zero dimensional fibers and all others are families of curves. We use the classification of familie...
متن کاملCircular pentagons and real solutions of Painlevé VI equations
We study real solutions of a class of Painlevé VI equations. To each such solution we associate a geometric object, a one-parametric family of circular pentagons. We describe an algorithm which permits to compute the numbers of zeros, poles, 1-points and fixed points of the solution on the interval (1,+∞) and their mutual position. The monodromy of the associated linear equation and parameters ...

We present an new system of ordinary differential equations with affine Weyl group symmetry of type E (1) 6 . This system is expressed as a Hamiltonian system of sixth order with a coupled Painlevé VI Hamiltonian. 2000 Mathematics Subject Classification: 34M55, 17B80, 37K10. Introduction The Painlevé equations PJ (J = I, . . . ,VI) are ordinary differential equations of second order. It is know...
متن کاملAsymptotic Properties of a Family of Solutions of the Painlevé Equation P VI
In analyzing the question whether nonlinear equations can define new functions with good global properties, Fuchs had the idea that a crucial feature now known as the Painlevé property (PP) is the absence of movable (meaning their position is solution-dependent) essential singularities, primarily branch-points, see [8]. First order equations were classified with respect to the PP by Fuchs, Brio...
