Title: Covering Systems of Congruences
Abstract: A conjecture by Alphonse de Polignac led Paul Erdos to develop the idea of covering systems of the integers around 1950. We will give some examples of covering systems and preliminary results, as well as discuss two famous problems posed by Erdos that have fascinated some mathematicians for the last seventy years. Additionally, we will examine the strong relationship between covering systems and Sierpinski and Riesel numbers.
