Bounds on the number of zeros of a quadratic form
Thanks! I guess I have sorted out the situation using your previous comments. |

Bounds on the number of zeros of a quadratic form
Thanks for the reference. I mentioned that particular form as an example, but I am indeed interested in dimensions 3 and 4. I will look up Fricke and Klein. |

Bounds on the number of zeros of a quadratic form
Will Jagy: Here is an example: Take (say) the form $Q(x,y,z)=x^2+y^2-5z^2$. Suppose I want to have solutions $(x,y,z)$ to $Q(x,y,z)=0$ such that $x$ is not divisible by a certain prime number $p$. Is there a guarantee I can get $cT log T$ of them with $|x|,|y|,|z|<T$? |

Dear few_reps: I have read your answer and am trying to see if I can make your proof and the one given below by Paul work for SO(Q). Please repost your answer. I will give feedback soon. |
