In this paper, we consider the discrete power function associated with the sixth Painlevé equation. This function is a special solution of the so-called crossratio equation with a similarity ...

Introduces students to ideas and techniques from discrete mathematics that are widely used in science and engineering. Mathematical definitions and proofs are emphasized. Topics include formal logic ...

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 ...
