| Abstract | When the origin of a nonlinear system having a parameter is locally asymptotically stable, the size of its basin of attraction may also depend on the parameter. If the parameter variation is confined within a compact interval and if the origin is locally exponentially stable for each parameter, then it is well-known that the radius of basin of attraction does not shrink to zero under the variation of parameter. We relax this condition up to the case where the origin loses exponential stability for a certain parameter. This is done by focusing on the behavior of the system on a parametrized center manifold. In addition, by introducing the concept of stability with respect to a positively invariant subset of the state-space, the proposed analysis is applicable to the case where the system experiences bifurcation of splitting or merging equilibria, which often appears in biological systems. The stability property considered here is called for with the boundary layer system in the singular perturbation context, or with the system having slowly varying inputs. The main results establish that the non-vanishing basin of attraction (relative to a positively invariant set) is guaranteed by confirming the similar property just for the reduced order system on a parametrized center manifold. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
