New (3+1)-dimensional integrable fourth-order nonlinear equation: lumps and multiple soliton solutions

What is it about?

We introduce a new (3+1)-dimensional fourth-order integrable equation characterized by second-order derivative in time $t$. The new equation models both right and left-going waves in a like manner to the Boussinesq equation. The newly developed model furnishes multiple soliton solutions and lump solutions.
