Tropical Laurent series, their tropical roots, and localization results for the eigenvalues of nonlinear matrix functions
Gian Maria Negri Porzio, Vanni Noferini, Leonardo Robol
Tropical roots of tropical polynomials have been previously studied and used to localize roots of classical polynomials and eigenvalues of matrix polynomials. We extend the theory…
Hierarchical adaptive low-rank format with applications to discretized PDEs
Stefano Massei, Leonardo Robol, Daniel Kressner
A novel compressed matrix format is proposed that combines an adaptive hierarchical partitioning of the matrix with low-rank approximation. One typical application is the approxima…
Mixed precision recursive block diagonalization for bivariate functions of matrices
Stefano Massei, Leonardo Robol
Various numerical linear algebra problems can be formulated as evaluating bivariate function of matrices. The most notable examples are the Fréchet derivative along a direction, th…
