Abstract
This paper deals with the systematical checking of the possible equality of two functions or what is the same, of two expressions. The nature of the problem is first considered. The concept of Universe is reexamined. The concepts of Object Attribute Power Table, Prime Universe, Prime Table and Canonical Expression, unique for each class of equivalent functions, are introduced. A procedure to determine the Canonical Expression is presented.
