Query: Novel curved solitons of integrable (2 +1) dimensional KMN equation   In this letter, the unique exact lump and topological soliton solutions of
integrable (2+1) dimensional Kundu Mukherjee Naskar (KMN) equation are
obtained. These solutions have an unusual property that they can get curved in
the plane arbitrarily due to the presence of an arbitrary function of space(x)
and time(t) in their analytic forms. Due to this special feature, the solutions
can be used to model the bending of optical solitonic beam, different types of
wave structures in real physical experimental conditions. This novel feature,
which is a rare property for a constant coefficient completely integrable
equation, arises due to the Galilean co-variance property and current like
nonlinearity present in the KMN equation.
