Abstract: In the paper, we consider large-scale differential matrix equations nonsymmetric T-Riccati and T-Sylvester. These matrix equations appear in many applications such as control theory, transport theory, macroeconomics and policy dynamics, and others. So far, it presents an unexplored problem in numerical analysis, theoretical results, and computational methods, which are lacking in the literature. In this paper, we show how to apply Krylov methods such as the extended block Arnoldi algorithm to get low-rank approximate solutions. The initial problem is projected onto subspace to get ...
