Abstract

In this paper we investigate guessing number, a relatively new concept linked to network coding and certain long standing open questions in circuit complexity. Here we study the bounds and a variety of properties concerning this parameter. As an application, we obtain the lower and upper bounds for shift graphs, a subclass of directed circulant graphs.
