Kileel's degree-independent bound conjecture for powers of polynomials

Let dd, kk, and ss be positive integers, and let p1,,pkR[x1,,xd]p_1,\ldots,p_k\in\mathbb{R}[x_1,\ldots,x_d] be homogeneous polynomials of the same degree ss, no two of which are linearly dependent over R\mathbb{R}. For sufficiently large rr, the powers p1r,,pkrp_1^r,\ldots,p_k^r are linearly independent; Proposition~ denotes a bound with this property by r~=r~(d,k,s)\tilde{r}=\tilde{r}(d,k,s). Kileel's degree-independent bound conjecture. In the setting of Proposition~, r~\tilde{r} may be taken to depend only on dd and kk. This conjecture asks whether the threshold for linear independence can be chosen independently of the common degree ss; the paper's abstract states that the conjecture is proved, with the resulting explicit bound given there.
