Abstract: | By means of a method of analytic number theory the following theorem is proved. Letp be a quasi-homogeneous linear partial differential operator with degreem,m > 0, w.r.t a dilation given by ( a1, …, an). Assume that either a1, …, an are positive rational numbers or for some Then the dimension of the space of polynomial solutions of the equationp[u] = 0 on ℝn must be infinite |
