Supernovae Distribution and Host Galaxy Properties
  We present the summary of our last results on the spatial distribution and
relative frequencies of Supernovae (SNe) in a large number of host galaxies
from the Sloan Digital Sky Survey (SDSS). We use the locations of SNe in order
to study the relations between radial/azimuthal distributions of SNe and
properties of their hosts and environments. On the other hand, the vertical
distribution of SNe allows to study the progenitors association to the thin or
thick discs, and to the stellar halo. We also propose the underlying mechanisms
shaping the number ratios of SNe types. It is important to note that there were
no extended studies of the 3D distribution of SNe and structural parameters of
hosts. Our study is intended to fill this gap and better constrain the nature
of SN progenitors.
