Tree successor algebra: A new branch in mathematics – E-bok Typ:E-bok Hans Botwid och Hjalmar GullbergTree successor algebra: A new branch in mathematics is a book about a formal theory of tree generation with an axiomatic basis for a new object called collection space. The elements of this space, in other words collections, have a clear connection to rooted trees and are treated as variables in sum form equations, the application area of tree successor algebra. With connections to different branches of mathematics such as number theory, linear
