| Summary: | In this thesis, we study the construction of algebraic lattices, tracing our steps back
to the foundational concepts in the theory of the Geometry of Numbers introduced by
Hermann Minkowski where lattices are built over number fields. Building upon this
groundwork, we explore recent advancements, particularly the work of Hou Xiaolu [8],
who extended this construction to quaternion algebras over number fields. We contribute
to this theory by providing a generator matrix for her construction, which illuminates the
geometric perspective and allows us to give a closed form volume formula. Additionally, we
present a construction for the renowned E8 lattice. Finally, we lay down the foundations to
broaden this construction to cyclic algebras over number fields, showcasing how quaternion
algebras can be viewed as a special case, corresponding to a degree 2 case of cyclic algebras. |
