Oct 10, 2017 at 18:22 comment added reuns What about starting from $\Lambda \supset \mathfrak{b}\Lambda$ lattices in $K$ and $\displaystyle T_\ell\ [\mathbb{C}/\Lambda, \mathbb{C}/\mathfrak{b}\Lambda]=\sum_{\mathfrak{c}, (\Lambda :\mathfrak{c}\Lambda)= \ell}[\mathbb{C}/\mathfrak{c}\Lambda, \mathbb{C}/\mathfrak{b}\mathfrak{c}\Lambda ]=\sum_{\mathfrak{c} \in Pic(\ell)}[\mathbb{C}/\mathfrak{c}\Lambda, \mathbb{C}/\mathfrak{b}\mathfrak{c}\Lambda]$ where $\mathfrak{c}$ are lattices in $K$ and $Pic(\ell)$ is the ideal classes of some order.
