review text: This paper discusses the vanishing of Tor modules and homological dimensions of unions of unions of aCM schemes. In particular, the authors give some generalization when one of the two schemes has codimension 2 and apply this result to the monomial case. The reviewer thinks it is important and useful for the study of homological dimensions.
