Computing critical points for algebraic systems defined by hyperoctahedral invariant polynomials

Thi Xuan Vu

Let $K$ be a field of characteristic zero and $K [x_{1}, \dots, x_{n}]$ the corresponding multivariate polynomial ring. Given a sequence of $s$ polynomials $\mathbf{f}…

Rank-Sensitive Computation of the Rank Profile of a Polynomial Matrix

George Labahn, Vincent Neiger, Thi Xuan Vu +1

Consider a matrix $F \in K [x]^{m \times n}$ of univariate polynomials over a field $K$ . We study the problem of computing the column rank profile of $\ma…
