|Abstract||Formal derivation of relativistic dispersion relations for the associated production of strange particles by pion-nucleon collision is presented without trying to give rigorous proof of derivation concerning the analytic continuation of the causal amplitudes into the unphysical region. Matrix structure of causal amplitudes in spin that the asymptotic solutions should contain only positive integer powers of meson emission operators. The possibility that the asymptotic solution for the ground state will give a good description of the situation at small distances from the core of nucleons is displease delete the above lines------starting with (that the asymptotic solutions should contain only posi-) and isospoin space is studied.. Dispersion relations are obtained in covariant form as well as in Breit system separately for spin-flip or nonspin-flip and isospin-flip or nonisospin-flip processes of the associated production.

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
