%0 Journal Article %T Discrete surfaces of constant mean curvature %A F Burstall %A U Hertrich-Jeromin %A W Rossman %A S Santos %J Mathematics %D 2008 %I arXiv %X We propose a unified definition for discrete analogues of constant mean curvature surfaces in spaces of constant curvature as a special case of discrete special isothermic nets. B\"acklund transformations and Lawson's correspondence are discussed. It is shown that the definition generalizes previous definitions and a construction for discrete cmc surfaces of revolution in space forms is provided. %U http://arxiv.org/abs/0804.2707v1
