The Gauss circle problem concerns the difference P2(n) between the area of a circle of radius n and the number of lattice points it contains. In this paper, we study the Dirichlet series with coefficients P2(n)2, and prove that this series has meromorphic continuation to . Using this series, we prove that the Laplace transform of P2(n)2 satisfies 0P2(t)2etXdt = CX32 X + O(X12+𝜖), which gives a power-savings improvement to a previous result of Ivić (1996).

Similarly, we study the meromorphic continuation of the Dirichlet series associated to the correlations r2(n + h)r2(n), where h is fixed and r2(n) denotes the number of representations of n as a sum of two squares. We use this Dirichlet series to prove asymptotics for n1r2(n + h)r2(n)enX, and to provide an additional evaluation of the leading coefficient in the asymptotic for nXr2(n + h)r2(n).
