abstract = {We present the result of a search for the
charged-lepton-flavor violating decays $τ^- \rightarrow
e^\mp \ell^\pm \ell^-$, where $\ell$ is a muon or an
electron, using a data sample with an integrated luminosity
of 428 fb$^{-1}$ recorded by the Belle II experiment at the
SuperKEKB $e^+e^-$ collider. The selection of $e^+e^-
\toτ^+τ^-$ events containing a signal candidate is based
on an inclusive-tagging reconstruction and on a boosted
decision tree to suppress background. Upper limits on the
branching fractions between 1.3 and 2.5 $\times 10^{-8}$ are
set at the 90\% confidence level. These results are the most
stringent bounds to date for four of the modes.},
