| The additive structure of algebraic integers in totally real number fields has been of great interest in the last ten years, partly due to its connection to universal quadratic forms. While the case of real quadratic fields is fairly well understood, the student will focus on the higher degree case where much less is known. The student will also consider more general problems concerning subsemigroups of lattices, motivated by extending the known results on numerical semigroups, as well as applications of these results to various topics such as quadratic forms. |
