Query: Study of the Dependence of the Plateau Shape for Type II Supernovae on
  Metallicity   We consider the effect of a change in the rate of flux decline in the U band
for type II-P supernovae (SNe IIP) as a function of metallicity $Z$. Based on
this effect, we propose a new method to determine the photometric redshift from
the SN IIP light curve in the U band. Using the STELLA code, we have
constructed model light curves in different bands for different redshifts $z =
0.0, 0.1$, and $0.3$ as the metallicity in the models decreases from $Z \sim
10^{-3}$ to $\sim 10^{-6}$. The flux in the U band is shown to reach a plateau
at the lowest metallicities. We consider the influence of other parameters as
well: the presupernova mass and the mass of radioactive nickel-56.
