Abstract

In this paper, we introduce concise expressions for the complex Bessel integral that enables us to improve the spectral large sieve inequality of Watt for PGL2(Z[i])\PGL2(C)\mathrm{PGL}_2 (\mathbb{Z}[i]) \backslash \mathrm{PGL}_2 (\mathbb{C}). Our result is optimistic in the case when the average of spectral parameters is on a square centered at (0,0)(0, 0).
