Abstract
We consider a class of one-dimensional Heisenberg spin models (plaquet te chains) related to the recently found 1/5-depleted square-lattice H eisenberg system CaV4O9. A number of exact and exact-numerical results concerning the properties of the competing dimer and resonating plaqu ette phases are presented. (C) 1997 Elsevier Science B.V.
