Query: Lepton flavor violation via four-Fermi contact interactions at the
  International Linear Collider   Lepton flavor violating (LFV) process $e^+ e^- \to e^+ \tau^-$ induced by the
four-Fermi contact interactions at the International Linear Collider (ILC) is
studied. Taking account of the event selection conditions, it is shown that the
ILC is sensitive to smaller LFV couplings as compared to the measurement of
$\tau\to 3e$ process at the B-factory experiment. The upper bounds on some of
the LFV couplings are improved by several factors using polarized $e^-/e^+$
beams at $\sqrt{s}=250~\mathrm{GeV}$ and by an order of magnitude at
$\sqrt{s}=1~\mathrm{TeV}$.
