Streszczenie
Let be a homogeneous polynomial with rational coefficients in d variables. We prove several results concerning uniform simultaneous approximation to points on the graph of f, as well as on the hypersurface \{f(x_1,\dots,x_d) = 1\}. The results are first stated for the case f(x_1,\dots,x_d) = x_1^2+\dots+x_d^2, which is of particular interest.
