Eisenstein series for O(2,n+2)

Aloys Krieg, Felix Schaps, Hannah Römer

We will characterize the Eisenstein series for O(2, n + 2) as a particular Hecke eigenform. As an application we show that it belongs to the associated Maaß space. If the underlyin…

Fourier coefficients of Eisenstein series for $O^{+} (2, n + 2)$

Felix Schaps

We derive the Fourier expansion of scalar-valued Eisenstein series for O(2, n+2) using classical methods of Siegel, Braun, Zagier, Bruinier and others. We assume that the underlyin…

Maximal Discrete Subgroups of $S O^{+} (2, n + 2)$

Aloys Krieg, Felix Schaps

We characterize the maximal discrete subgroups of $S O^{+} (2, n + 2)$ , which contain the discriminant kernel of an even lattice, which contains two hyperbolic planes over $Z$ . T…
