Does anyone know results about the existance of initial model (in Cat or other categories) of 2-sketch or V-sketch with indexed limits, and that of other equivalent (or more general) formulations (e.g. higher-dimensional sketch of Power and Wells)? I think of results analogous to the existance of the (family of) initial model in Set of FL or FLS sketch. Any relevant informations and references are much welcome. Thanks in advance. ---- Hiroyuki Miyoshi Department of Mathematics, Faculty of Science and Technology, Keio Univ.
