Fröberg conjecture

In algebraic geometry, the Fröberg conjecture is a conjecture about the possible Hilbert functions of a set of forms. It is named after Ralf Fröberg, who introduced it in Fröberg (1985, page 120). The Fröberg–Iarrobino conjecture is a generalization introduced by Iarrobino (1997).
