Cusp Forms Like Δ
Let $f$ be a square-free integer and denote by ${{\Gamma }_{0}}{{\left( f \right)}^{+}}$ the normalizer of ${{\Gamma }_{0}}\left( f \right)$ in $\text{SL}\left( 2,\,\mathbb{R} \right)$ . We find the analogues of the cusp form $\Delta$ for the groups ${{\Gamma }_{0}}{{\left( f \right)}^{+}}$ .

| Zusammenfassung: | Let
$f$
be a square-free integer and denote by
${{\Gamma }_{0}}{{\left( f \right)}^{+}}$
the normalizer of
${{\Gamma }_{0}}\left( f \right)$
in
$\text{SL}\left( 2,\,\mathbb{R} \right)$
. We find the analogues of the cusp form
$\Delta$
for the groups
${{\Gamma }_{0}}{{\left( f \right)}^{+}}$
