Giving a polynomial, say
a x^2 + b x y + c y^2
MonomialList[a x^2 + b x y + c y^2, {x, y}]
just gives
{a x^2, b x y, c y^2}
How can I get a list without the coefficients? I mean, the following list
{x^2, x y, y^2}
The motivation of this question is, I am only interested in the structure of the polynomial itself, i.e., which kinds of of monomials are there, while their explicit coefficient are not relevant.
