Abstract
Approximate real-space (cell-type) renormalization-group methods are used to calculate the surface tension between coexisting phases in two- and three-dimensional Ising models. The results are physically reasonable and show the expected scaling properties near a critical point. However, there are some problems in reconciling the three-dimensional results with the existence of a roughening transition.Keywords
