Title: Enumerating Orders in Number Fields
Abstract: For a given number field K we study the distribution of suborders of the maximal order O_K of K. The Chinese Remainder Theorem shows that it suffices to describe the orders whose index in O_K is a power of p for some prime p.
Zassenhaus' well-known Round 2 algorithm yields an effective method to compute the p-maximal order of a given order in K. We show how to reverse this process to enumerate the orders of a given prime power index in O_K.

Symmetry and Graph Coloring: Algebraic and Combinatorial Mysteries
📄 ABSTRACT / RÉSUMÉ
The study of proper colorings of graphs is a longstanding and important area in mathematics. The Four Color theorem for planar graphs is one famous success, and this simple problem in cartography launched a vast theory leading to many concrete applications, as well as to the algebraic study of chromatic polynomials and symmetric functions, which also arise in the geometry of Hessenberg varieties.
