Pretrees and arborescent convexities
A. V. Malyutin St. Petersburg Department of Steklov Institute of Mathematics RAN, Fontanka 27, 191023 St. Petersburg, Russia
Abstract:
We prove that the class of pretrees, the theory of which is developed by L. Ward [11], B. Bowditch [2], S. Adeleke and P. Neumann [1], and others, is canonically isomorphic to the class of arborescent convexity spaces introduced by P. Duchet [6] in the framework of abstract convexity theory.
Key words and phrases:
tree, pretree, dendritic, arborescent, betweenness, convexity, Carathéodory number, variety, interval space.
