Classical Solution of the Wave Equation [PDF]
International Journal of Modern Physics A, 2003 The classical limit of wave quantum mechanics is analyzed. It is shown that the basic requirements of continuity and finiteness to the solution of the form ψ(x) = Aei ϕ (x) + Be-i ϕ (x), where [Formula: see text] and W(x) is the reduced classical action of the physical system, give the asymptote of the wave equation and general quantization condition ...

OLD PROBLEMS, CLASSICAL METHODS, NEW SOLUTIONS [PDF]
International Journal of Theoretical and Applied Finance, 2020 We use a powerful extension of the classical method of heat potentials, recently developed by the present author and his collaborators, to solve several significant problems of financial mathematics. We consider the following problems in detail: (a) calibrating the default boundary in the structural default framework to a constant default intensity ...

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023 Background. A huge number of mathematical models are called Boussinesq equations; therefore, a wide range of sixth-order Boussinesq equations attracts a lot of attention from outside researchers around the world. Materials and methods.

High‐Order Time‐Dependent Perturbation Theory for Classical Mechanics and for Other Systems of First‐Order Ordinary Differential Equations [PDF]
, 1970 A time‐dependent perturbation solution is derived for a system of first‐order nonlinear or linear ordinary differential equations. By means of an ansatz, justified a posteriori, the latter equations can be converted to an operator equation which is ...

Classical Solutions for the Generalized Korteweg-de Vries Equation
Axioms, 2023 The Korteweg-de Vries equation models the formation of solitary waves in the context of shallow water in a channel. In our system, f or p=2 and p=3 (Korteweg-de Vries equations (KdV)) and (modified Korteweg-de Vries (mKdV) respectively), these equations ...

On exact solution of a classical 3D integrable model [PDF]
, 1999 We investigate some classical evolution model in the discrete 2+1 space-time. A map, giving an one-step time evolution, may be derived as the compatibility condition for some systems of linear equations for a set of auxiliary linear variables.
