Resultant multiplicity via projective degrees and applications to tensor eigenvalues

Mahmut Levent Doğan, Elias Tsigaridas, Zafeirakis Zafeirakopoulos

Given a system of homogeneous forms in variables of the same degree, Macaulay's resultant vanishes precisely when the polynomials have a commo…

Exact Algebraic Computation of Learning Coefficients for Two-Dimensional Singular Models

Grégoire Sergeant-Perthuis, Elias Tsigaridas, Jules Tsukahara

Classical information criteria such as the Bayesian Information Criterion (BIC) rely on regularity assumptions that break down for singular models, leading to incorrect model selec…

Small Resultant Systems via Linear Combinations

M. Levent Doğan, Elias Tsigaridas, Zafeirakis Zafeirakopoulos

For a system of homogeneous polynomials of degree in variables, say , we consider the problem of constructing resultant systems. A resultant system is a f…

Optimal Preconditioning is a Geodesically Convex Optimization Problem

M. Levent Doğan, Alperen Ergür, Elias Tsigaridas

We introduce a unified framework for computing approximately-optimal preconditioners for solving linear and non-linear systems of equations. We demonstrate that the condition numbe…

Beyond Worst-Case Analysis for Symbolic Computation: Root Isolation Algorithms

Alperen A. Ergür, Josué Tonelli-Cueto, Elias Tsigaridas

We introduce beyond-worst-case analysis into symbolic computation. This is an extensive field which almost entirely relies on worst-case bit complexity, and we start from a basic p…

Bounds on the infimum of polynomials over a generic semi-algebraic set using asymptotic critical values

Boulos El Hilany, Elias Tsigaridas

We present precise bit and degree estimates for the optimal value of the polynomial optimization problem , where is a semi-al…
