Black Holes and Wormholes in 2+1 Dimensions,is a negative cosmological constant. The classical theory of such locally “anti-de Sitter” spaces is treated in an elementary way, using visualizable models. Among the objects discussed are black holes, spaces with multiple black holes, their horizon structure, closed universes, and the topologies t

Open Inflation,et it satisfied the no boundary condition and came from an instanton of finite size, with a mass of the order of one gram. Our paper aroused a lot of interest, as shown by 37 citations on HEP-TH, but it brought a lot of opposition. This centered on three features of our model..First, we were attacke

nd biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legum

Productive research in the former was initiated with the preparation of active cell-free extracts in 1960, but characterization work did not get well under way until into the mid-19
