Equations with Rapidly Oscillating Solutions,, the equations of elasticity, the Schrödinger equation, the Dirac equation, and others. There are also nonlinear equations having analogous solutions. Interest in these solutions is becoming immense in theoretical and mathematical physics (the short-wave approximation, the high-frequency approximation, the quasi-classical approximation, etc.).
