Abstract
Some aspects of the relation between proofs of both absence and existence of phase transitions for a class of quantum spin systems and their classical counterparts are discussed. The results of absence of phase transitions apply to a large class of classical systems with special symmetry already considered by Vuillermot and Romerio (1975), and to their quantum mechanical analogues.Keywords
