Alternative Integration Procedure for Scale - Invariant Ordinary Differential Equations Gerald
For an ordinary differential equation invariant under a one-parameter )tly’ y" )te-2 group of scale transformations x / %x, y + %=y, y’ / / y etc., it is shown by example that an explicit analytical general solution may be obtainable in parametric form in terms of the scale-invariant variable x 1/a ydx. This alternative integration may go through, as it does for the example equation y" kxyy’, i...
متن کاملInvariant functions for solving multiplicative discrete and continuous ordinary differential equations
In this paper, at first the elemantary and basic concepts of multiplicative discrete and continous differentian and integration introduced. Then for these kinds of differentiation invariant functions the general solution of discrete and continous multiplicative differential equations will be given. Finaly a vast class of difference equations with variable coefficients and nonlinear difference e...
متن کاملIntegration of Ordinary Differential Equations
where z is a new variable. This exemplifies the procedure for an arbitrary ODE. The usual choice for the new variables is to let them be just derivatives of each other (and of the original variable). Occasionally, it is useful to incorporate into their definition some other factors in the equation, or some powers of the independent variable, for the purpose of mitigating singular behavior that ...
متن کاملIntegration of Ordinary Differential Equations
The solution of differential equations is an important problem that arises in a host of areas. Many differential equations are too difficult to solve in closed form. Instead, it becomes necessary to employ numerical techniques. Differential equations have a major application in understanding physical systems that involve aerodynamics, fluid dynamics, thermodynamics, heat diffusion, mechanical o...
