Terry Plattra go. This global decomposition generalizes the polar decomposition of matrices. The group . contains the center of . and, if the center of . is finite, is a maximal compact subgroup of ...The Iwasawa decomposition . exhibits closed subgroups . and . of . such that . is simply connected abelian, .

Ron Johnsonted as a sequence of problems, as it had been in the first draft of the seminar‘s notes. We believe that solving these problems may help the reader to feel the seminar‘s atmosphere and master the theory. Nevertheless, all the non-trivial ideas, and sometimes solutions, are contained in hints given a

D. Strangeoup and of Lie group. A natural harmonic analysis arises on hypergroups, while any abstract transformation of Fourier type is gen­ erated by some hypergroup (commutative or not). Part III contains papers on the geometry of homogeneous spaces, Lie algebras and Lie superalgebras. Classical problems of

Chris Plichtmutative ring yields an .-ring homomorphism. There is a duality between symmetric products of topological spaces and the set of all .-ring homomorphisms from the ring of functions on the space to C. The development of the properties of .-ring homomorphisms involves a number of combinatorial identiti

Mount Tuffley Observatory in Gloucester, England,stro-photography had a great advantage over visual observation for deep-sky work: one can indeed easily record far greater structural detail in extended objects, and record much fainter stellar objects than can be seen visually. This is the case even when making the shortest of time exposures and using the small-aperture camera lens or telescope.
