"Topological and Algebraic Structures in Fuzzy Sets" is strategically located at the juncture of fuzzy sets, topology, algebra, lattices and foundations of mathematics. It contains major studies in uniformities and convergence structures, fundamental examples in lattice-valued topology, modifications and extensions of sobriety, categorical aspects of lattice-valued subsets, logic and foundations of mathematics, t-norms and associated algebraic and ordered structures. Internationally recognized authorities clarify deep mathematical aspects of fuzzy sets, particularly those topological or algebraic in nature.
