Hello people in mapleprimes,
I want to collect
aa:=sigma*omega*alpha = mu(H, H)*s*omega*gamma*L+omega^(-sigma+1)*tau*mu(F, F)*s*L-omega^(-sigma+1)*tau*mu(F, F)*s*L*gamma;
with omega^(-sigma+1);

I know that the above expression could be collected with tau, which
produces the same expression as the one collected with omega^(-sigma).
And, in collecting with omega^(-sigma+1), I know that freeze-thaw could be used.

But, I want to know another way to do the same thing, using frontend or 
subsindets. Is this possible?

Thanks in advance.
