Hey! :o

Is someone familiar with the following?

We have linear differential equations with polynomial coefficients depending on x.

$a_n(x)y^{(n)}+ \dots a_1(x)y^{(1)}+a_0(x)y^{(0)}=b(x)$

There are problems like if there are solutions, if the solutions are linear independent and so on and we are looking for the decidability and the complexity.
 
Hi,

I'm not too much familiar with this questions, but ... don't you need an algorithm to talk about the complexity? Or are you asking about the existence of a polynomial time algorithm?
 
First of all, I am asking if someone is familiar with the decidability of such problems.

Are you familiar with that?
 
One such problem is the following:

Do you maybe know where I can get more information?

Is this related to the 10th problem of Hilbert?
