Combined invariant subspace & frequency-domain subspace method for identification of discrete-time MIMO linear systems [PDF]
Systems and Control Letters, 2023 Recently, a novel system identification method based on invariant subspace theory is introduced, aiming to address the identification problem of continuous-time (CT) linear time-invariant (LTI) systems by combining time-domain and frequency-domain methods.

A new method for computing the stable invariant subspace of a real Hamiltonian matrix [PDF]
Journal of Computational and Applied Mathematics, 1997 The problem of the numerical computation of the Lagrangian invariant subspaces of a real Hamiltonian matrix with a strongly backward stable algorithm is thoroughly examined. The solution of the Hamiltonian eigenvalue problem is important because of its close relation with the solution of the continuous-time algebraic Riccati equation.

Speed invariant gait recognition—The enhanced mutual subspace method
PLOS ONE, 2021 This paper introduces anenhanced MSM(Mutual Subspace Method) methodology for gait recognition, to provide robustness to variations in walking speed. Theenhanced MSM (eMSM)methodology expands and adapts the MSM, commonly used for face recognition, which is a static/physiological biometric, to gait recognition, which is a dynamic/behavioral biometrics ...

A refined invariant subspace method and applications to evolution equations [PDF]
Science China Mathematics, 2012 The invariant subspace method is refined to present more unity and more diversity of exact solutions to evolution equations. The key idea is to take subspaces of solutions to linear ordinary differential equations as invariant subspaces that evolution equations admit.

Invariant Subspace Method: A Tool for Solving Fractional Partial Differential Equations [PDF]
Fractional Calculus and Applied Analysis, 2017 In this paper invariant subspace method has been employed for solving linear and non-linear fractional partial differential equations involving Caputo derivative. A variety of illustrative examples are solved to demonstrate the effectiveness and applicability of the method.

Communications in Nonlinear Science and Numerical Simulation, 2022 In this paper, we generalize the theory of the invariant subspace method to (m + 1)-dimensional non-linear time-fractional partial differential equations for the first time. More specifically, the applicability and efficacy of the method have been systematically investigated through the (3 + 1)-dimensional generalized non-linear time-fractional ...

The parameterization method for invariant manifolds I: Manifolds associated to non-resonant subspaces [PDF]
Indiana University Mathematics Journal, 2003 We introduce a method to prove existence of invariant manifolds and, at the same time to find simple polynomial maps which are conjugated to the dynamics on them. As a first application, we consider the dynamical system given by a Cr map F in a Banach space X close to a fixed point: F(x) = Ax + N(x), A linear, N(0) = 0, DN(0) = 0. We show that if X1 is

Analytic solution of nonlinear fractional Burgers-type equation by invariant subspace method [PDF]
, 2013 In this paper we study the analytic solutions of Burgers-type nonlinear fractional equations by means of the Invariant Subspace Method. We first study a class of nonlinear equations directly related to the time-fractional Burgers equation. Some generalizations linked to the forced time-fractional Burgers equations and variable-coefficient diffusion are
