Cosmic microwave background anisotropies and the large scale structure of the universe

We discuss the implications of the COBE/DMR detection of Cosmic Microwave Background anisotropies on inflationary models for the large scale structure of the universe. We also discuss the constraints set on these models from current upper limits on the Cosmic Microwave Background anisotropies at small and intermediate angular scales, and from the local abundance of X-ray galaxy clusters.
