Rational curves on Grassmannians: systems theory, reality, and transversality
Frank Sottile
We discuss a particular problem of enumerating rational curves on a Grassmannian from several perspectives, including systems theory, real enumerative geometry, and symbolic comput…
Elementary Transversality in the Schubert calculus in any Characteristic
Frank Sottile
We give a characteristic-free proof that general codimension-1 Schubert varieties meet transversally in a Grassmannian and in some related varieties. Thus the corresponding interse…
An excursion from enumerative goemetry to solving systems of polynomial equations with Macaulay 2
Frank Sottile
Solving a system of polynomial equations is a ubiquitous problem in the applications of mathematics. Until recently, it has been hopeless to find explicit solutions to such systems…
Some real and unreal enumerative geometry for flag manifolds
Frank Sottile
We present a general method for constructing real solutions to some problems in enumerative geometry which gives lower bounds on the maximum number of real solutions. We apply this…
