[#P12923] Exact-Gamma Four-Swap Asymptotics for Long Mellin-Radial Amplifiers in the Gaussian Angular Hecke Family
Contents
Problem. Let \(\lambda\) be the Gaussian angular Hecke character on the nonzero integral ideals of \(\mathbb Z[i]\), defined on principal ideals by \(\lambda((z))=(z/|z|)^4\), and put \(L_k(s)=L(s,\lambda^k)\) for \(k\ge 1\). Fix \(\Phi\in C_c^\infty((1,2))\), a real number \(0<\vartheta<1/2\), and set \(X=K^\vartheta\). Fix a compact set \(T\subset\mathbb R\) and a sufficiently large integer \(J\). For each \(K\), let \(F_K\in C_c^\infty((0,1))\) satisfy \[ \sup_K\sum_{j=0}^{J}\int_{\mathbb R}(1+|\xi|)^J\left|\partial_\xi^j\widehat F_K(\xi)\right|\,d\xi<\infty, \] where \(\widehat F_K(\xi)=\int_{\mathbb R}F_K(u)e^{-iu\xi}\,du\). For \(t_0\in T\), define \[ a_{\mathfrak a}=(N\mathfrak a)^{-1/2-it_0}F_K\!\left(\frac{\log N\mathfrak a}{\log X}\right),\qquad A_k(a)=\sum_{\mathfrak a}a_{\mathfrak a}\lambda(\mathfrak a)^k, \] and \(\|a\|_2^2=\sum_{\mathfrak a}|a_{\mathfrak a}|^2\). Define \[ \mathcal M_K(\alpha,\beta;a)=\sum_{k\ge1}\Phi(k/K)L_k(1/2+\alpha)L_k(1/2+\beta)|A_k(a)|^2. \] Put \(L_0(s)=\zeta(s)L(s,\chi_{-4})\) and \[ Z(\gamma,\delta)=\frac{\zeta(1+2\gamma)\zeta(1+2\delta)L_0(1+\gamma+\delta)}{\zeta(2+2\gamma+2\delta)}. \] For integral ideals \(\mathfrak n\), define \[ \tau_{\gamma,\delta}(\mathfrak n)=\sum_{\mathfrak r\mathfrak s=\mathfrak n}N\mathfrak r^{-\gamma}N\mathfrak s^{-\delta}. \] For a nonzero ideal \(\mathfrak l\), write \(\mathfrak l=(q_{\mathfrak l})\mathfrak l^\circ\), where \((q_{\mathfrak l})\) is the largest ideal generated by a positive rational integer dividing \(\mathfrak l\). If \(\mathfrak p^d\Vert\mathfrak l^\circ\), define \[ P_{\mathfrak p^d}(\gamma,\delta)=\frac{N\mathfrak p^{-d/2}}{1+N\mathfrak p^{-1-\gamma-\delta}}\left(\tau_{\gamma,\delta}(\mathfrak p^d)-N\mathfrak p^{-1-2\gamma-2\delta}\tau_{\gamma,\delta}(\mathfrak p^{d-2})\right), \] with \(\tau_{\gamma,\delta}(\mathfrak p^j)=0\) for \(j<0\), and set \[ P_{\mathfrak l}(\gamma,\delta)=\prod_{\mathfrak p^d\Vert\mathfrak l^\circ}P_{\mathfrak p^d}(\gamma,\delta). \] This convention includes the ramified prime above \(2\); rational ideal content does not change the angular twist.
For \(s\in\mathbb C\), define \[ X_k(s)=\pi^{2s}\frac{\Gamma(2k+\tfrac12-s)}{\Gamma(2k+\tfrac12+s)} \] and, for \(\epsilon_1,\epsilon_2\in\{\pm1\}\), \[ G_{\epsilon_1,\epsilon_2}(k;\alpha,\beta)=X_k(\alpha)^{(1-\epsilon_1)/2}X_k(\beta)^{(1-\epsilon_2)/2}. \] Define the exact-gamma four-swap main term by \[ \begin{aligned} \mathcal M_K^{(4),\mathrm{exact}}(\alpha,\beta;a)=&\sum_{\epsilon_1,\epsilon_2=\pm1}\sum_{k\ge1}\Phi(k/K)G_{\epsilon_1,\epsilon_2}(k;\alpha,\beta)\\ &\times\sum_{\mathfrak a,\mathfrak b}a_{\mathfrak a}\overline{a_{\mathfrak b}}\,Z(\epsilon_1\alpha,\epsilon_2\beta)P_{\mathfrak a\overline{\mathfrak b}}(\epsilon_1\alpha,\epsilon_2\beta). \end{aligned} \] The combined four-sector expression is interpreted by common meromorphic continuation whenever separated terms have removable singularities. Define \[ H_k(\alpha,\beta)=\pi^{\alpha+\beta}\frac{\Gamma(2k+\tfrac12)^2}{\Gamma(2k+\tfrac12+\alpha)\Gamma(2k+\tfrac12+\beta)}. \] Call a compact set \(\Omega\subset\mathbb C^2\) regular if the combined four-sector meromorphic expression has no nonremovable pole on \(\Omega\). The collision divisors \(\alpha=0\), \(\beta=0\), \(\alpha+\beta=0\), and \(\alpha-\beta=0\) may be included when the combined expression has a removable continuation there.
Prove that for every fixed regular compact \(\Omega\), every \(\varepsilon>0\), and every fixed \(0<\vartheta<1/2\), uniformly for \((\alpha,\beta)\in\Omega\), \(t_0\in T\), and all packets \(F_K\) satisfying the stated norm condition, \[ \mathcal M_K(\alpha,\beta;a)=\mathcal M_K^{(4),\mathrm{exact}}(\alpha,\beta;a)+O_{\Omega,\vartheta,T,\Phi,J,\varepsilon}\!\left(K^{1/2+\varepsilon}\sup_{k\asymp K}|H_k(\alpha,\beta)|\,\|a\|_2^2\right), \] with no hidden factor \(X^\delta\) for any fixed \(\delta>0\). Equivalently, by uniform Stirling asymptotics on every fixed regular compact \(\Omega\), \[ \mathcal M_K=\mathcal M_K^{(4),\mathrm{exact}}+O_{\Omega,\vartheta,T,\Phi,J,\varepsilon}\!\left(K^{1/2-\Re(\alpha+\beta)+\varepsilon}\|a\|_2^2\right). \] The endpoint \(\vartheta=1/2\) and shift ranges growing with \(K\) are excluded.
