 Author Comment/Response Michael 11/14/12 8:17pm I have this long formula after a fourier transform and non of the transformations seem to be working with any of the assumptions I've tried. I'm trying to group the coefficients in front of the deltas: [code]-(1/8) I \[Pi] (A Conjugate[ A] DiracDelta[-1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] + I B Conjugate[ A] DiracDelta[-1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] + I A Conjugate[ B] DiracDelta[-1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] - B Conjugate[ B] DiracDelta[-1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] - 2 A Conjugate[A] DiracDelta[ w\[Alpha]] DiracDelta[-4 + w\[Theta]] - 2 I B Conjugate[A] DiracDelta[ w\[Alpha]] DiracDelta[-4 + w\[Theta]] - 2 I A Conjugate[B] DiracDelta[ w\[Alpha]] DiracDelta[-4 + w\[Theta]] + 2 B Conjugate[B] DiracDelta[w\[Alpha]] DiracDelta[-4 + w\[Theta]] + A Conjugate[A] DiracDelta[ 1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] + I B Conjugate[A] DiracDelta[ 1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] + I A Conjugate[B] DiracDelta[ 1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] - B Conjugate[B] DiracDelta[ 1 + w\[Alpha]] DiracDelta[-4 + w\[Theta]] - 2 I B Conjugate[ A] DiracDelta[-1 + w\[Alpha]] DiracDelta[-2 + w\[Theta]] + 2 I A Conjugate[ B] DiracDelta[-1 + w\[Alpha]] DiracDelta[-2 + w\[Theta]] + 2 I B Conjugate[A] DiracDelta[ 1 + w\[Alpha]] DiracDelta[-2 + w\[Theta]] - 2 I A Conjugate[B] DiracDelta[ 1 + w\[Alpha]] DiracDelta[-2 + w\[Theta]] + 2 I B Conjugate[A] DiracDelta[-1 + w\[Alpha]] DiracDelta[ w\[Theta]] + 2 I A Conjugate[B] DiracDelta[-1 + w\[Alpha]] DiracDelta[ w\[Theta]] + 8 I A Conjugate[A] DiracDelta[w\[Alpha]] DiracDelta[w\[Theta]] + 4 I B Conjugate[A] DiracDelta[w\[Alpha]] DiracDelta[w\[Theta]] + 4 I A Conjugate[B] DiracDelta[w\[Alpha]] DiracDelta[w\[Theta]] + 8 I B Conjugate[B] DiracDelta[w\[Alpha]] DiracDelta[w\[Theta]] + 2 I B Conjugate[A] DiracDelta[1 + w\[Alpha]] DiracDelta[ w\[Theta]] + 2 I A Conjugate[B] DiracDelta[1 + w\[Alpha]] DiracDelta[ w\[Theta]] - 2 I B Conjugate[A] DiracDelta[-1 + w\[Alpha]] DiracDelta[ 2 + w\[Theta]] + 2 I A Conjugate[B] DiracDelta[-1 + w\[Alpha]] DiracDelta[ 2 + w\[Theta]] + 2 I B Conjugate[A] DiracDelta[1 + w\[Alpha]] DiracDelta[ 2 + w\[Theta]] - 2 I A Conjugate[B] DiracDelta[1 + w\[Alpha]] DiracDelta[ 2 + w\[Theta]] - A Conjugate[A] DiracDelta[-1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + I B Conjugate[A] DiracDelta[-1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + I A Conjugate[B] DiracDelta[-1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + B Conjugate[B] DiracDelta[-1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + 2 A Conjugate[A] DiracDelta[w\[Alpha]] DiracDelta[4 + w\[Theta]] - 2 I B Conjugate[A] DiracDelta[w\[Alpha]] DiracDelta[ 4 + w\[Theta]] - 2 I A Conjugate[B] DiracDelta[w\[Alpha]] DiracDelta[ 4 + w\[Theta]] - 2 B Conjugate[B] DiracDelta[w\[Alpha]] DiracDelta[4 + w\[Theta]] - A Conjugate[A] DiracDelta[1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + I B Conjugate[A] DiracDelta[1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + I A Conjugate[B] DiracDelta[1 + w\[Alpha]] DiracDelta[ 4 + w\[Theta]] + B Conjugate[B] DiracDelta[1 + w\[Alpha]] DiracDelta[4 + w\[Theta]])[/code] If anybody has any ideas I'd be very grateful.
