Theorem: The set of computable functions is closed under composition. Proof: Given computable f and g, we wish to show that g∘f is computable. Let S be a Turing machine that computes f, and T a Turing machine that computes g, such that the states of S and T are disjoint. Let ...

Computable functions in tabular databasesWe provide a formalization of data structures used in tabular databases. A tabular computable function is defined. A finite base of the algebra of computable tabular functions is constructed, using the operations multiply, branch, loop, and parallel execution....
