¿unsolved problems in differential equations?

jonjacson

Hi, I would like to talk with you about the modern lines of investigation about differential equations ( ode,pde...) , which are the most interesting unsolved questions, ecuations to solve, general tools for solving differential equations ....


I know we have learned a lot, but still there is a lot of work to do .

I know a professor who when asked after a colloquium talk to state one of the most important unsolved problems in differential equations stepped to the chalkboard and wrote:

[tex] y' = f(x,y)[/tex]

and sat down.

Yes most equations can't be solved analyticly...

He should be more precise, I think that you could demonstrate the exixtence and uniqueness of a solution using Picard's method.

Perhaps he was asking for a general method to find the solution?

Here's one with a prize ...
