WebWikipedia WebHeck, basis vectors in crystallography aren't even linearly independent. You can have a 3D crystal structure where the unit cell contains a large number of atoms. Then you have way more than 3 basis vectors, who can't possibly be linearly independent. Basis vector in crystallography ≠ basis vector in linear algebra. – Lagerbaer May 7, 2013 at 13:58 the origins of chess

WebJan 25, 2024 · Crystal Lattice or Space lattice is an arrangement of points regularly repeating in space. As it is a repeating arrangement, to describe the space lattice well, we can choose a small part of the lattice, which produces the complete space lattice when repeated in different directions. This small portion of the lattice is called the ‘unit cell.’ WebCrystal base theory was developed by Kashiwara and Lusztig from the perspective of quantum groups. Its power comes from the fact that it addresses many questions in representation theory and mathematical physics by combinatorial means. This book approaches the subject directly from combinatorics, building crystals through local …
