Boolean function

&#9758; This page belongs to resource collections on Logic and Inquiry.

A finitary boolean function is a function of the form $$f : \mathbb{B}^k \to \mathbb{B},$$ where $$\mathbb{B} = \{ 0, 1 \}$$ is a boolean domain and where $$k\!$$ is a nonnegative integer. In the case where $$k = 0,\!$$ the function is simply a constant element of $$\mathbb{B}.$$

There are $$2^{2^k}$$ such functions. These play a basic role in questions of complexity theory as well as the design of circuits and chips for digital computers.
