CLASSICAL SCHOTTKY GROUPS OF REAL TYPE OF GENUS TWO, III

Dedicated to Professor Fumiyuki Maeda on his sixtieth birthday

Abstract

There are eight kinds of classical Schottky spaces of real type of genus two. In this paper we consider the spaces of the third, sixth and eighth types. This paper has the following three aims: (1) to represent the shape of the spaces by using multipliers and cross ratios of the fixed points of two generators; (2) to find generators for the Schottky modular groups acting on the above spaces; (3) to determine fundamental regions for the Schottky modular group acting on the spaces.
