**Discrete Mathematics Group at URI**

The faculty of our group is interested in a wide range of areas in discrete mathematics
both pure and applied: graph theory, network theory, extremal and probabilistic methods,
analytic methods, finite model theory, combinatorial games, combinatorial optimization,
bioinformatics applications.

Title | On gaps in the gaussian primes |

Time | Friday April 21, 2023, 1pm, Lippitt 204 |

Abstract | It is known that one cannot walk to infinity on the real line using only primes and steps of bounded length. We will survey what is known on the same problem for Gaussian primes in Z[i]. The later problem is presently unresolved. The MS presentation is based on papers by M. Das (Walking through the Gaussian Primes) and by E. Gethner, S. Wagon, B. Wick (A Stroll through the Gaussian Primes). |
