Curves in Grassmannians are analyzed using the special structure of th
e tangent bundle of a Grassmannian, resulting in a theory of inflectio
ns or Weierstrass behavior. A duality theorem is established, generali
zing the classical duality theorem for projective plane curves. The ap
pendices summarize basic information about principal parts bundles and
their application to studying the inflections of curves in projective
space.
