Bücher von Joaquim Gabarro

This is the second volume of a two volume collection on Structural Complexity. This volume assumes as a prerequisite knowledge about the topics treated in Volume I, but the present volume itself is nearly self-contained.

This result was already included in our Volume II, but we feel that due to the basic nature of the result, it belongs to this volume. For the sake of the reader of Volume II, where all references to Volume I follow the old numbering, we have included here a table indicating the new number corresponding to each of the old ones.
