Using group analysis methods, for the Ovsyannikov equation with maximal symmetry which describes steady oscillations in a continuously inhomogeneous medium we obtain an exact solution to the boundary value problems for some regions (a generalized Poisson formula), which in particular can serve as test solutions for simulating steady oscillations in continuously inhomogeneous media. We find operators acting on the set of solutions in a one-parameter family of these equations.
Mots-clés : Ovsyannikov equation
Keywords: maximal symmetry, steady oscillations in continuously inhomogeneous medium, intertwining operators, generalized Poisson formula.
