We calculate the number of irreducible components of varieties
in $(\mathbb C^*)^n$ determined by generic systems of equations
with given Newton polytopes. Every such component can in its turn
be given by a generic system of equations whose Newton polytopes
are found explicitly. It is known that many discrete invariants
of a variety can be found in terms of the Newton polytopes. Our
results enable one to calculate such invariants for each
irreducible component of the variety.
Keywords:
Newton polytopes, mixed volume, irreducible components, holomorphic forms.
