Devoted to various constructions of sets which are nonmeasurable with respect to invariant measures. This work begins by explaining the classical Vitali theorem stating the existence of subsets of the real line which are not measurable in the Lebesgue sense.

From a detailed analysis of hypercomplex numbers in up to four dimensions, Silviu Olariu presents hypercomplex number properties in five and six dimensions and on to an analysis of polar and planar hypercomplex numbers in n dimensions.

Studies automorphism groups of both graphs and maps. This book includes chapters on the subfields of enumerative topological graph theory and random topological graph theory, as well as on the composition of English church-bell music. It places emphasis on Cayley maps: imbeddings of Cayley graphs for finite groups.

Contains 32 articles on various areas of functional analysis and its applications: Banach spaces and their geometry, operator ideals, Banach and operator algebras, operator and spectral theory, Frechet spaces and algebras, function and sequence spaces.
