Graphs and Circle-Systems,er first the orthogonal-circle representation (abbreviated as OCR) of a special type of graphs, called quadrangulations. An OCR of a graph is a circle-system consisting of circles each corresponding to a vertex of the graph, in which each pair of circles corresponding to a pair of adjacent vertices

Quartets on a Sphere,proved by showing that any given region on a sphere contains a quartet (i.e., a four-point space) that is not isometrically embeddable in the plane. Actually, any region on a sphere contains a quartet whose six distances determine the radius of the sphere uniquely. Moreover, we present an equation t
