Joining of decorated trees
 Journal of Formalized Mathematics

"... Summary. This is the continuation of the sequence of articles on trees (see [2], [4], [5]). The main goal is to introduce joining operations on decorated trees corresponding with operations introduced in [5]. We will also introduce the operation of substitution. In the last section we dealt with tre ..."

Summary. This is the continuation of the sequence of articles on trees (see [2], [4], [5]). The main goal is to introduce joining operations on decorated trees corresponding with operations introduced in [5]. We will also introduce the operation of substitution. In the last section we dealt with trees decorated by Cartesian product, i.e. we showed some lemmas on joining operations applied to such trees.
Sets and functions of trees and joining operations of trees
 Journal of Formalized Mathematics
, 1992
"... Summary. In the article we deal with sets of trees and functions yielding trees. So, we introduce the sets of all trees, all finite trees and of all trees decorated by elements from some set. Next, the functions and the finite sequences yielding (finite, decorated) trees are introduced. There are sh ..."

Summary. In the article we deal with sets of trees and functions yielding trees. So, we introduce the sets of all trees, all finite trees and of all trees decorated by elements from some set. Next, the functions and the finite sequences yielding (finite, decorated) trees are introduced. There are shown some convenient but technical lemmas and clusters concerning with those concepts. In the fourth section we deal with trees decorated by Cartesian product and we introduce the concept of a tree called a substitution of structure of some finite tree. Finally, we introduce the operations of joining trees, i.e. for the finite sequence of trees we define the tree which is made by joining the trees from the sequence by common root. For one and two trees there are introduced the same operations.

this paper. 1. Preliminaries For simplicity, we adopt the following rules: S is a non void non empty many sorted signature, U 1 , U 2 , U 3 are nonempty algebras over S, I is a set, A is a many sorted set indexed by I , and B, C are nonempty many sorted sets indexed by I . The following four propositions are true: (1) For every binary relation R and for all sets X , Y such that X ` Y holds (R#Y ) ffi X = R ffi X: (2) Let A be a set, B, C be non empty sets, f be a function from A into B, g b
