= Harish-Chandra's Ξ function
{wiki=Harish-Chandra's_Ξ_function}
Harish-Chandra's Ξ function, often denoted as \\( \\Xi(s) \\), is a special function in the field of representation theory and number theory, related to automorphic forms and the theory of L-functions. It is particularly significant in the study of the spectral decomposition of automorphic forms and the Langlands program. Specifically, the Ξ function emerged in the context of automorphic representations of reductive groups over global fields.
