Abstract:

Using the concepts of type and relative type for points in $\beta N - N$, as introduced by W. Rudin, M. E. Rudin, and Z. Frolik, an inductive method is presented for constructing types. The relative types are described for points having these constructed types and a point in $\beta N - N$ is found which has exactly $c$ relative types.
