Before revision:  The primal Bregman Voronoi diagram is the Euclidean Voronoi diagram and the dual Bregman Voronoi diagram coincides with the Cauchy hyperbolic Voronoi diagram.
After revision:  The primal Bregman Voronoi diagram is the Euclidean Voronoi diagram and the dual Bregman-Tsallis Voronoi diagram coincides with the Cauchy hyperbolic Voronoi diagram.
