A diagram of the discrete function shows a distinct point that remains unconnected. While in a continuous function graph, the points are connected with an unbroken line.

In this paper we construct the main ingredients of a discrete function theory in higher dimensions by means of a new "skew" type of Weyl relations. We will show that this new type overcomes the ...

I'm taking my first discrete math course. One aspect of functions has me stumped. We're asked to list the functions from a two-element set to a three-element set. And then list all the functions ...
