Hello,
I have a problem with the use of FeynCalc.
After some manipulations I get (scalar) expression which depends on several external vectors.I need to make expansion over one of them (k) up to O(k^2)-terms.

However the use of internal function
FourDivergence[....] doesn't help-FeynCalc tries to take the derivative for arbitrary momenta(which is too complicated) and doesn't give result(The program ran several days).

Does anybody knows, If it is possible to make such expansion at k=0 ?
(i.e. is there any function like Series[...] which would make expansion over VECTOR without evaluation of the derivatives ?)

Thanks in advance,
Ivan Petrov
