Query: Emergent Universe with Exotic Matter in Brane World Scenario   In this work, we have examined the emergent scenario in brane world model for
phantom and tachyonic matter. For tachyonic matter field we have obtained
emergent scenario is possible for closed, open and at model of the universe
with some restriction of potential. For normal scalar field the emergent
scenario is possible only for closed model and the result is identical with the
work of Ellis et al [2], but for phantom field the emergent scenario is
possible for closed, open and at model of the universe with some restriction of
potential.
