Tensor decomposition and homotopy continuation
Alessandra Bernardi, Noah S. Daleo, Jonathan D. Hauenstein +1
A computationally challenging classical elimination theory problem is to compute polynomials which vanish on the set of tensors of a given rank. By moving away from computing polyn…
Multiprojective witness sets and a trace test
Jonathan D. Hauenstein, Jose Israel Rodriguez
In the field of numerical algebraic geometry, positive-dimensional solution sets of systems of polynomial equations are described by witness sets. In this paper, we define multipro…
Software for the Gale transform of fewnomial systems and a Descartes rule for fewnomials
Daniel J. Bates, Jonathan D. Hauenstein, Matthew E. Niemerg +1
We give a Descartes'-like bound on the number of positive solutions to a system of fewnomials that holds when its exponent vectors are not in convex position and a sign condition i…
Certifying isolated singular points and their multiplicity structure
Jonathan D. Hauenstein, Bernard Mourrain, Agnes Szanto
This paper presents two new constructions related to singular solutions of polynomial systems. The first is a new deflation method for an isolated singular root. This construc-tion…
Homotopy techniques for tensor decomposition and perfect identifiability
Jonathan D. Hauenstein, Luke Oeding, Giorgio Ottaviani +1
Let T be a general complex tensor of format . When the fraction is an integer, and a natural inequality (called balancedness) is satis…
