Abstract:The object of this paper is to describe an explicit two-parameter family of logarithmic flat connections over the complex projective plane. These connections have dihedral monodromy and their polar locus is a prescribed quintic composed of a conic and three tangent lines. By restricting them to generic lines we get an algebraic family of isomonodromic deformations of the five-punctured sphere. This yields new algebraic solutions of a Garnier system. Finally, we use the associated Riccati oneforms to construct … Show more
