Asymptotic behavior of flat surfaces in hyperbolic 3-space
Masatoshi Kokubu, Wayne Rossman, Masaaki Umehara +1
In this paper, we investigate the asymptotic behavior of regular ends of flat surfaces in the hyperbolic 3-space H^3. Galvez, Martinez and Milan showed that when the singular set d…

Derived Schwarz map of the hypergeometric differential equation and a parallel family of flat fronts
Takeshi Sasaki, Kotaro Yamada, Masaaki Yoshida
In the previous paper (math.CA/0609196) we defined a map, called the hyperbolic Schwarz map, from the one-dimensional projective space to the three-dimensional hyperbolic space by…
