文摘
We study the decomposition of a degree \(d\) homogeneous linear form \(f\in K[x_0,\dots ,x_n]\) as a sum of \(x\) \(d\) -powers of linear forms in \(x_0,\dots ,x_n\) and \(y\) \(d\) -powers of \(x_1,\dots ,x_n\) . Most of our results are for cases with \(ny \le \left( {\begin{array}{c}n+d-1\\ n-1\end{array}}\right) \) and with \(d\ge 5\) . If \(n\le 4\) , we also consider the cases \(d=3,4\) . We also study other interpolation problems (e.g., flags instead of a hyperplane).
