Dear mathgroupers,
I am currently working with polynomials which are made up of
terms of the form:
p q
ZETA ZETB
--------------- * S[something]
r
(ZETA + ZETB)
and I want to substitute the part in ZETx with A[p,q,r]. In order
to do that, I use the following substitution command:
(ZETA^p_. *ZETB^q_. *S[something])*(ZETA + ZETB)^r_. -> A[p,q,-r]
but this does not work in cases where p,q or r = 0. Section 2.3.1 of
the mma book by Wolfram says to look in section 2.3.9, which I did,
but I still could not figure out how to achieve this goal.
Does anyone out there knows how ?? thanks in advance, martin
