Feb 3, 2011 at 22:08 comment added Leonid Dworzanski Concerning J.D.Farley - not sure that his posets are trees, but will try. Thank you! In TCS it's more about using trees as data structures, or algorithms on trees etc
Feb 3, 2011 at 21:57 comment added Gerhard Paseman Also, I used trees to model terms in a language. You might consider asking in Theoretical Computer Science forums for some examples of literature. Gerhard "Ask Me About System Design" Paseman, 2011.02.03
Feb 3, 2011 at 21:54 comment added Gerhard Paseman I doubt that you will find exactly the book you want. You might start with conference proceedings on Algebras and Orders. Someone who might have some good pointers for you is J. D. Farley. Gerhard "Ask Me About System Design" Paseman, 2011.02.03
Feb 3, 2011 at 21:52 comment added Leonid Dworzanski There is a way to define order on trees like: The tree $a \in \mathbb{T}$ is less than the tree $b \in \mathbb{T}$ if there is the injection $j:N \rightarrow N$ between their nodes which preserves incidence relation. ($\mathbb{T}$ - universum of trees, $N$ - set of nodes). And there is a way to define operation $+:\mathbb{T}\times\mathbb{T}\rightarrow\mathbb{T}$ as if we consider trees as multisets of multisets of $\dots$ of leaves. But this operation isn't a group operation. So I'm looking for books about such relations, operations etc.
Feb 3, 2011 at 18:28 comment added Pete L. Clark Well, from my question you can see that I won't be able to supply the references you want, but: what do you mean by an order, algebra or ordered group on a tree?
