Dear All,
I am working on the solution of an ordinary differential equation. Among others related to a given Ansatz I get a long set of sums I want to sort and order in dependency of terms like
((x/(-1 + x))^(expnt)
with the exponents "expnt"
1/4, 1/2, 3/4
to do this, I put something like this to my code
Collect[q, {((x/(-1 + x))^(1/4)), ((x/(-1 + x))^(1/
2)), ((x/(-1 + x))^(3/4))}]
the result provides summands of the type
const ((x/(-1 + x))^(expnt) x^n / (-1+x)^m
where n, m are integers.
Unfortunately there are 4 summands, which do not behave like this. They show exponents of order 19/4, 15/4 and 7/4
Obviously I have to tune the Collect code line.
My question to the experts:
Would you please give me a hint to tune my Collect code line to avoid the above mentioned exponents.
Additionally I added an nb-File to reproduce the problem and because of the large number of summands a PDF of my output showing the problem summands marked with a red box.
Regards,
drnie
