1,2-rational N-soliton solutions for difference–differential equations related to the Volterra equation

We present a new 1-rational N-soliton solution for the Volterra equation. We also present an additional note on 1,2-rational N-soliton solutions for already-known equations related to the Volterra equation. Next, we present a new representation of an already-known 1-rational N-soliton solution for the discrete MKdV equation and a new 1-rational N-soliton solution for the discrete KdV equation. Lastly, we present 1-rational N-soliton solutions for the difference–differential equations related to the discrete MKdV equation.
