Description
We consider a Higgs bundle $(E, \phi)$. Its Higgs Grassmiannans are subschemes of the usual Grassmannian bundles of $E$ that parameterise Higgs quotients of $(E, \phi)$. We recall how to define them, present some results about their structure, and explain how they can be used to prove some results about Higgs bundles satisfying a strong semistability condition.
