The problem of proving superpolynomial lower bounds on sizes of formulas computing an explicit polynomial is one of the important open questions in complexity theory. The same applies to more restricted computational models, such as homogeneous formulas. In particular, it is not known whether homogeneous formulas are more powerful than unrestricted formulas.

I will illustrate this problem on the example of elementary symmetric polynomials, which are natural candidates for a potential separation.
