Hi,
I am trying to solve a system of functional equations using
perturbation methods. I have equations the left side of which look
like, for example,
exp:delta*S(t,e)+M*beta*S(t,e)*v(t,e)^alpha*u(t,e)^(1-alpha)+M*(1-beta)*S
(t,e)*v(t,e)^alpha*v(t,e)^-alpha;
I would like to bring diff(exp,e) to the form
diff(v(t,e),e)*A + diff(u(t,e),e)*B + diff(S(t,e),e)*C
and get a list [A,B,C]. I tried reading the archives, and found
facsum, but
facsum(diff(exp,e),diff(v(t,e),e));
does not quite do what I want: fractions remain in the whole thing (I
want something "flat"), and I don't know how to extract the
expressions that correspond to A,B,C above.
Thanks,
Tamas
PS.: sorry if this appears more than once, it didn't go through gmane the
first time.
