Many soliton equations, their solutions and their properties, can be deduced from simpler (essentially linear) equations involving more complicated objects, e.g., integral operators. The deduction process from the operator-valued equation to the scalar one amounts to some rather simple procedure like taking a trace or a determinant. This is described for the class of soliton equations solvable with the Zakharov–Shabat spectral transform.
