Unified framework for Fiedler-like strong linearizations of polynomial and rational matrices
Ranjan Kumar Das, Harish K. Pillai
Linearization is a widely used method for solving polynomial eigenvalue problems (PEPs) and rational eigenvalue problem (REPs) in which the PEP/REP is transformed to a generalized…

Structured strong linearizations of structured rational matrices
Ranjan Kumar Das, Rafikul Alam
Structured rational matrices such as symmetric, skew-symmetric, Hamiltonian, skew-Hamiltonian, Hermitian, and para-Hermitian rational matrices arise in many applications. Lineariza…
