Abstract
We prove the general properties of morphisms of Chu spaces and functors with a value in the category 𝐶ℎ𝑢(𝑆𝑆 − 𝐴𝑐𝑡) of Chu spaces over the category 𝑆𝑆 − 𝐴𝑐𝑡. As a consequence, for the category 𝐶ℎ𝑢(𝑆𝑆 −𝐴𝑐𝑡) the existence of coproducts and some products is proved, monomorphisms and epimorphisms are characterized; in terms of this category the characteristics of separable and complete separable Chu spaces are given.
