Abstract

Let 0 and 1 denote the null and unit elements of a Boolean algebra B. The following four functions with argument in B and values in B are of fundamental importance in Boolean algebra. They are: the null function, defined by 0x = 0; the unit function, defined by 1x = 1; the identity function j, defined by jx = x, and the complementary function c, defined by the rule, ex is the complement of x. These four functions, 0, 1, j, c, form a tri-operational algebra in the sense of Karl Menger.
