Query: Density of integer solutions to diagonal quadratic forms   Let Q be a non-singular diagonal quadratic form in at least four variables.
We provide upper bounds for the number of integer solutions to the equation
Q=0, which lie in a box with sides of length 2B, as B tends to infinity. The
estimates obtained are completely uniform in the coefficients of the form, and
become sharper as they grow larger in modulus.
