Inhaltsangabe:
- In this paper, we introduce higher level versions of the theta group $Γ_θ.$ In particular, we treat level 3 and 4 versions of the theta group, $Γ_{θ,3}$ and $Γ_{θ,4}$ and prove that $\displaystyle F(τ)=η\left(\frac{τ-1}{3} \right) η\left(\frac{τ+1}{3} \right)$ and $\displaystyle G(τ)=η\left(\frac{τ-1}{4} \right) η\left(\frac{τ+1}{4} \right)$ are modular forms on $Γ_{θ,3}$ and $Γ_{θ,4}$ respectively. Moreover we compute their multiplier systems, $ν_{F}$ and $ν_{G}$.
