| Abstract | This paper studies a stochastic linear-quadratic (LQ) control problem over an infinite time horizon with Markovian jumps in parameter values, allowing the weighting matrices in the cost to be indefinite. Coupled generalized algebraic Riccati equations (CGAREs) involving pseudo inverse of a matrix are introduced. It is shown that the solvability of the LQ problem boils down to that of the CGAREs. However, the system of the CGAREs is hard to treat. To overcome this difficulty, the corresponding semidefinite programming (SDP) and related duality are utilized. Several implication relations among the SDP complementary duality, the existence of the solution to the CGAREs and the optimality of LQ problem are established. A numerical procedure that provides a thorough treatment of the LQ problem via primal-dual SDP is presented: it identifies a stabilizing optimal feedback control or determines that the LQ problem has no optimal solution |

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.
