Query: Noncommutativity in interpolating string: A study of gauge symmetries in
  noncommutative framework   A new Lagrangian description that interpolates between the Nambu--Goto and
Polyakov version of interacting strings is given. Certain essential
modifications in the Poission bracket structure of this interpolating theory
generates noncommutativity among the string coordinates for both free and
interacting strings. The noncommutativity is shown to be a direct consequence
of the nontrivial boundary conditions. A thorough analysis of the gauge
symmetry is presented taking into account the new modified constraint algebra,
which follows from the noncommutative structures and finally a smooth
correspondence between gauge symmetry and reparametrisation is established.
