Doubling condition at the origin for non-negative positive definite functions

We study upper and lower estimates as well as the asymptotic behavior of the sharp constant C=Cn(U,V) in the doubling-type condition at the origin 1|V|∫Vf(x)dx≤C1|U|∫Uf(x)dx, where U,V⊂ℝn are 0-symmetric convex bodies and f is a non-negative positive definite function.
