The inhomogeneous arithmetic transfer conjecture

Let F/F0F/F_0 be ramified and let n3n\geq3 be odd. Let S(F0)S(F_0) be the inhomogeneous symmetric space, let U0U_0 and U1U_1 be the relevant unitary groups, let K0U0(F0)K_0\subset U_0(F_0) be the chosen compact subgroup, and let Int(g)\operatorname{Int}(g) denote the intersection number for gU1(F0)rsg\in U_1(F_0)_{\mathrm{rs}}. Inhomogeneous arithmetic transfer conjecture. (a) There exists fCc(S(F0))f'\in C_c^\infty(S(F_0)) transferring to (1K0,0)(\mathbf{1}_{K_0},0) such that

2ω(γ)∂Orb(γ,f)=Int(g)logq2\omega(\gamma)\operatorname{\partial Orb}(\gamma,f')=-\operatorname{Int}(g)\cdot\log q

for every matching pair γS(F0)rs\gamma\in S(F_0)_{\mathrm{rs}} and gU1(F0)rsg\in U_1(F_0)_{\mathrm{rs}}. (b) For every such ff' there exists fcorrCc(S(F0))f'_{\mathrm{corr}}\in C_c^\infty(S(F_0)) such that

2ω(γ)∂Orb(γ,f)=Int(g)logq+ω(γ)Orb(γ,fcorr)2\omega(\gamma)\operatorname{\partial Orb}(\gamma,f')=-\operatorname{Int}(g)\cdot\log q+\omega(\gamma)\operatorname{Orb}(\gamma,f'_{\mathrm{corr}})

for every such matching pair. This is the ramified arithmetic-transfer prediction, with part (b) allowing a correction by an ordinary orbital integral.
