Projection Granular Space in Formal Concept

The object of this paper is object projection granular space and the attribute projection granular space. The generating method of granular coordination was given by projection granular space family, and using this coordination, we achieve a general method to compose and decompose any concept lattice, which avoid the strict condition in decomposition of subdirect, Atlas, and tentorial, and greatly expand the utilization of composition and decomposition of any concept lattice, This paper show the condition of how a projection granular space become a regular space and define the disturbance and the response of a formal context, and using them realize the method to form the complete family of the regular projection granular space.
