| Abstract | Vague sets can distinguish the positive evidence from the negative evidence. But they only possess some simple operations such as intersection, union and complement of sets. Fusing Vague sets and fuzzy groups, Vague groups were proposed in 2005. Vague groups possess one type of the binary operations between elements. Some structures of Vague sets had been obtained. It is possible to further improve Vague groups by means of more operations between elements and the action of other objects on the Vague groups. In order to solve the problem, this paper presents the Vague rings and the Vague modules. The latter is one Vague group upon which the one Vague ring acts. In an Vague module, there are four types of operations: two types of operations in Vague ring, one type of operation in Vague group, and the operation between Vague ring and Vague group. Thus, this paper gives the six theorems: 1. the sufficient condition of the homomorphism commutative diagram of Vague modules; 2. the Vague free module are the Vague project modules; 3 some new internal and external structures of the project modules; 4. the uniqueness of project modules; 5. the Vague module is the direct sum of its Vague-submodules under the ascending chain condition; and 6. Vague Schur theorem. They add the new properties of internal and external algebraic structures to Vague groups. They have not been seen in literature about Vague groups. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
