摘要: 通过证明Wigner—Seitz原胞的体积等于原胞体积,说明第一布里渊区体积等于倒格子原胞体积;对于第n布里渊区和第n-1布里渊区建立保长同胚映射证明两者体积相等.

关键词: 布里渊区, 保长同胚, 反演对称性, Wigner—Seitz原胞

Abstract: By proving the equation of the volume of Wigner-Seitz primitive cell and the volume of primitive cell,we conclude that the volume of the first Brillouin zone is identical to the volume of reciprocal' s primitive cell. We establish an isometric hemeomorphism mapping between the n-th and ( n - 1 )-th Brillouin zone to prove the equation of their volume.

Key words: Brillouin zone, isometric hemeomorphism mapping, inversion symmetry, Wigner- Seitz primitive cell
