Hyperbolic Schwarz Map for the Hypergeometric Differential Equation
نویسندگان
چکیده
The Schwarz map of the hypergeometric differential equation is studied since the beginning of the last century. Its target is the complex projective line, the 2-sphere. This paper introduces the hyperbolic Schwarz map, whose target is the hyperbolic 3-space. This map can be considered to be a lifting to the 3-space of the Schwarz map. This paper studies the singularities of this map, and visualize its image when the monodromy group is a finite group or a typical Fuchsian group. General cases will be treated in a forthcoming paper.

Hyperbolic Schwarz Maps of the Airy and the Confluent Hypergeometric Differential Equations and Their Asymptotic Behaviors
The Schwarz map of the hypergeometric differential equation is studied first by Schwarz, and later by several authors for various generalizations of the hypergeometric equation. But up to now nothing is studied about the Schwarz map for confluent equations, mainly because such a map would produce just a chaos. Recently we defined the hyperbolic Schwarz map, and studied in several cases, includi...
متن کاملDerived Schwarz Map of the Hypergeometric Differential Equation and a Parallel Family of Flat Fronts
In the paper [7] we defined a map, called the hyperbolic Schwarz map, from the one-dimensional projective space to the three-dimensional hyperbolic space by use of solutions of the hypergeometric differential equation, and thus obtained closed flat surfaces belonging to the class of flat fronts. We continue the study of such flat fronts in this paper. First, we introduce the notion of derived S...

متن کاملAsymptotic Behavior of the Hyperbolic Schwarz Map at Irregular Singular Points
Geometric study of a second-order Fuchsian differential equation u′′ − q(x)u = 0, where q is rational in x, has been made via the Schwarz map as well as via the hyperbolic and the derived Schwarz maps ([SYY]). When the equation admits an irregular singularity, such a study was first made in [SY] treating the confluent hypergeometric equation and the Airy equation. In this paper, we study the hy...
متن کاملConfluence of Swallowtail Singularities of the Hyperbolic Schwarz Map Defined by the Hypergeometric Differential Equation
The papers [Gálvez et al. 2000, Kokubu et al. 2003, Kokubu et al. 2005] gave a method of constructing flat surfaces in the three-dimesnional hyperbolic space. Such surfaces have generically singularities, since any closed nonsigular flat surface is isometric to a horosphere or a hyperbolic cylinder. In the paper [Sasaki et al. 2006], we defined a map, called the hyperbolic Schwarz map, from the...
