Abstract. The article carries out the study of the global and local properties of the spaces of class L . The author considers the properties of this class spaces connected with various types of cardinal characteristics such as character, narrowness, weight. The results shown in this paper are an essential addition to the theory of dyadic compacts. The proof of the main results of this article is based on the use of modern mathematical methods.
