Integrable Parametrically Driven Nonlinear Dynamical System of Pseudo-Excitations on a Two-Leg Ladder Lattice. Explicitly Manageable Formulation, Інтеґровна параметрично урухомлювана нелінійна динамічна система псевдозбуджень на двоніжковій драбинчатій ґратці. Явно здійснéнне формулювання

<jats:p>The basic features of the integrable parametrically driven nonlinear dynamical system of pseudo-excitations on a two-leg ladder lattice are formulated in clear and understandable terms. The explicit but rather general realization of parametric drive suitable for the strict development of system’s Darboux–B¨acklund integration technique is proposed and described in details.</jats:p>
