In summary, The equation y' = q_0(x)+q_1(x) y+...+q_n(x) y^n is a non-linear ODE and does not have a specific name, but it is sometimes referred to as a generalized RODE. It does not have an analytical solution in the general case for n>2 and there is limited research on it. Different methods, such as integration and power series, have been attempted to solve it with varying degrees of success. Assuming analytic q_i's with overlapping convergence domains can lead to a solution in series form.

Any one knows how do you call an equation of the type:
[tex] y' = q_0(x)+q_1(x) y+...+q_n(x) y^n [/tex]
Maybe generalized RODE?

Why do you expect a more specific name for this non-linear ODE ?
 
  • #3
Well I didn't find an entry of this equation in wiki, or I didn't search well enough.

So is this its name?
 
  • #4
May be, there is no analytical solution known in the general case, for n>2.
 
  • #5
Do you have any references I can read more on the general case (I mean what has been done already with it)?
 
  • #6
Well I can do something like integrate the equation and get:
[tex] y = \int q_0(x) dx + \int q_1(x) y dx +...\int q_n(x) y^n dx [/tex]

and plug the y in the left in y in the intergals, I would get an infinite sequence, it maybe be good for numerical calculations, but still not analytical.

I can also plug in a power series with powers of x for y.

I guess all of these methods have been tried before.

If I assume that q_i's are analytic and have an overlapping convergence domain, I can show that there should be a solution in a series form.
