Abstract:
The question of creation of some classes of mathematical physics equations solution of which possesses preditermined properties is investigated. By means of the VKB transformation (Ventsel – Kramers
– Brillouin) classes of mathematical physics equations of the second order are constructed: ordinary differential equations and equations in private derivatives of the hyperbolic, parabolic and elliptic types,
solved in "reference" functions.
Keywords:the VKB transformation, "reference" equation, "reference" function, ordinary differential equations, equations in private derivatives of hyperbolic, parabolic and elliptic types.
