“Combinatorics
of
horospherical
varieties”
In
this
talk
we
finish
our
brief
introduction
of
horospherical
varieties
by
examining
their
combinatorial
interpretation.
In
the
case
of
toric
varieties,
we
have
a
combinatorial
interpretation
using
fans;
in
the
case
of
horospherical
varieties,
we
use
so-called
“coloured
fans”
which
account
for
the
colours
that
we
discussed
in
the
last
talk.
This
seminar
will
be
held
jointly
online
and
