The word barycentric is derived from the Greek word barys (heavy), and refers to center of gravity. Barycentric calculus is a method of treating geometry by considering a point as the center of gravit
Building on his books since 1988, Ungar (North Dakota U.) explains the current status of analytic hyperbolic geometry, which emerged from Einstein's addition of relativistically admissible velocities.
The concept of the Euclidean simplex is important in the study of n-dimensional Euclidean geometry. This book introduces for the first time the concept of hyperbolic simplex as an important concept in
