Attaching only one infinite tail , or even a countably infinite number of infinite tails, to each finite subpath does not produce all possible paths. As Cantor proved and WM cannot disprove. > Consider the following model for a complete infinite binary tree: The set of nodes is N = {1,2,3,...}, each such natural being a node. For each node n in N, its left child is defined to be 2*n + 0 in N and its right child is defined to be 2*n + 1 in N. A path is, by definition, a set of nodes which contains 1, and, for each node in it, contains exactly one child of that node. Until WM can produce some cogent reason why the above definition fails to be a binary tree, all his claims about such trees are proved wrong.

Please prove your assertion by showing which path I did not produce. But prove it by knowing only all nodes of all paths. Information exceeding the infinite sequence of nodes of each path is not acceptable in mathematics. > > Consider the following model for a complete infinite binary tree: > > The set of nodes is N = {1,2,3,...}, each such natural being a node. > > For each node n in N, > its left child is defined to be 2*n + 0 in N and > its right child is defined to be 2*n + 1 in N. > > A path is, by definition, a set of nodes which contains 1, and, > for each node in it, contains exactly one child of that node.

Every node has two child-nodes. Regards, WM

If yes, then it is the union of all natural numbers as well as the union of all initial segments of the ordered set of all natural numbers as well as the union of all these and itself, because {1, 2, 3, ...} U {1, 2, 3, ...} = {1, 2, 3, ...} If you see that this equation is true, then you acknowledge my argument. If you cannot see that, then either you are a matheologian or you have too little intelligence to understand it or both. Regards, WM

In my tree, none.

Every node has two child-nodes. Then WM concedes his errors. |
