How to simplify a polynomial in a order that I want?
Assume that I have a polynomial here, for example, $a^3 b^4 c^2$, the order of symbels is the dictionary order, $a>b>c$. But what if I want in a order $b>a>c$?
This is convenient for Abelian algebra, but inconvenient for non-Abelian algebra. Actually, I am using a Mathematica package about Quantum Notation by José Luis Gómez-Muñoz, and I want to reduce a series product of quantum operator to a normal order -- creation is always after annihilation, or creation is always to the left of annihilation.
So, what should I do? Could I add a condition to
Simplify? Or is there such a function in the package that I use?
