Query: Study of Gauge Symmetry of Some Field Theoretical Models Through the
  Lagrangian Formulation   Study of gauge symmetry is carried over the different interacting and
noninteracting field theoretical models through a prescription based on
lagrangian formulation. It is found that the prescription is capable of testing
whether a given model posses a gauge symmetry or not. It can successfully
formulate the gauge transformation generator in all the cases whatever
subtleties are involved in it. It is found that the prescription has the
ability to show a direction how to extend the phase space using auxiliary
fields to restore the gauge invariance of a theory. Like the usual phase space
the prescription is found to be equally powerful in the extended phase space of
a theory.
