Introduction to numerical algebraic geometry

  title={Introduction to numerical algebraic geometry},
  author={Andrew J. Sommese and Jan Verschelde and Charles W. Wampler},
In a 1996 paper, Andrew Sommese and Charles Wampler began developing a new area, “Numerical Algebraic Geometry”, which would bear the same relation to “Algebraic Geometry” that “Numerical Linear Algebra” bears to “Linear Algebra”.

A package to interlink the existing symbolic methods of Macaulay2 and the powerful engine of numerical approximate computations to exhibit performance competitive with the other homotopy continuation software.

Computing Tropical Curves via Homotopy Continuation

This work exploits a connection between amoebas and tropical curves to devise a method for computing tropical curves using numerical algebraic geometry and gives an implementation that is used to compute Newton polygons of A-polynomials of knots.

Nonlinear algebra in 3 D computer vision

I study computational algebraic geometry—an amusing, somewhat more broad name for this field is nonlinear algebra. This field is firmly anchored to its algorithmic techniques—traditionally, symbolic

General witness sets for numerical algebraic geometry

This work presents a general notion of witness set for subvarieties of a smooth complete complex algebraic variety using ideas from intersection theory, and introduces Schubert witness sets, which provide general witness sets for Grassmannians and flag manifolds.

Galois groups of Schubert problems via homotopy computation

This work shows by direct computation that the Galois group of the Schubert problem of 3-planes in ℂ 8 meeting 15 fixed 5-planes non-trivially is the full symmetric group S 6006.

Regularization and Matrix Computation in Numerical Polynomial Algebra

Regularization principles for reformulating the ill-posed algebraic problems, derive matrix computations arising in numerical polynomial algebra, as well as subspace strategies that substantially improve computational efficiency by reducing matrix sizes are developed.
