| contents | In this paper, we improve the error term in the prime geodesic theorem for the Picard manifold $ \mathrm{PSL}_2 (\mathbb{Z} {[i]}) \backslash \mathbb{H}^3 $. Instead of $ \mathrm{PSL}_2 (\mathbb{Z} {[i]}) \backslash \mathbb{H}^3 $, we establish a spectral large sieve inequality for symmetric squares over $\mathrm{PSL}_2 (\mathbb{Z} {[i]}) \backslash \mathrm{PSL}_2 (\mathbb{C}) $. This enables us to improve the bound $ O (T^{3+2/3+\varepsilon}) $ of Balkanova and Frolenkov into $ O (T^{3+1/2+\varepsilon}) $ for the second moment of symmetric square $L$-functions over $ \mathrm{PSL}_2 (\mathbb{Z} {[i]}) \backslash \mathbb{H}^3 $. The basic idea is to enlarge the spherical family $Π_c^{0} (T)$ of Maass cusp forms on $ \mathrm{PSL}_2 (\mathbb{Z} {[i]}) \backslash \mathbb{H}^3 $ into the family $ Π_c (T, \sqrt{T}) $ of cuspidal representations on $ \mathrm{PSL}_2 (\mathbb{Z} {[i]}) \backslash \mathrm{PSL}_2 (\mathbb{C}) $. |
