| Abstract | We present some of our previous results (1995, 1998) where we treat an optimal control problem for a nonlinear elliptic equation of the Volterra-Lotka type with homogeneous Dirichlet boundary conditions. This type of problems arises from population dynamics, where they model the steady-state solutions of the corresponding nonlinear evolution problem. We are interested in maximizing a functional which represents the difference between economic revenue and cost. Fist, we prove the existence of optimal control. Then, assuming that the quotient between the price of the species and the cost of the control is small, an optimality system is derived. This is used for proving the uniqueness and constructive approximation to the optimal control. In the proofs, we use different methods related to the theory of nonlinear elliptic equations and nonlinear analysis, such as upper and lower solutions notions, variational characterization of eigenvalues, weak maximum principles, strictly convex operators, etc. |

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.
