In mathematics, Kleene equality, [1] or strong equality, is an equality operator on partial functions, that states that on a given argument either both functions are undefined, or both are defined and their values on that arguments are equal.
The function can be constructed from the partial computable function (,) described above and the s-m-n theorem: for each , () is the index of a program which computes the function (,). To complete the proof, let F {\displaystyle F} be any total computable function, and construct h {\displaystyle h} as above.
The push operation increases the flow on a residual edge, and a height function on the vertices controls through which residual edges can flow be pushed. The height function is changed by the relabel operation. The proper definitions of these operations guarantee that the resulting flow function is a maximum flow.
The arrows or morphisms between sets A and B are the functions from A to B, and the composition of morphisms is the composition of functions. Many other categories (such as the category of groups, with group homomorphisms as arrows) add structure to the objects of the category of sets or restrict the arrows to functions of a particular kind (or ...
