Klee diagram is an important term in the field of algebraic number theory. It is a tool used to visualize certain splitting fields of number fields. It is also known as the Kummer-Vandiver diagram or the Hilbert-Speiser diagram. The diagram is named after the mathematician Victor Klee, who was the first to use it in his work. Some other synonyms of Klee diagram may include the LMFDB Kummer web, the Kummer lattice or the Kummer net. In short, all of these terms are used to describe a visual representation of a certain algebraic structure.
