Linear-Quadratic Mean Field Control: The Hamiltonian Matrix and Invariant Subspace Method [PDF]
2018 IEEE Conference on Decision and Control (CDC), 2018 This paper studies the existence and uniqueness of a solution to linear quadratic (LQ) mean field social optimization problems with uniform agents. We exploit a Hamiltonian matrix structure of the associated ordinary differential equation (ODE) system and apply a subspace decomposition method to find the solution.

On polynomial solutions of differential equations
, 1992 A general method of obtaining linear differential equations having polynomial solutions is proposed. The method is based on an equivalence of the spectral problem for an element of the universal enveloping algebra of some Lie algebra in the ...

DOA Estimation for Sources with Large Power Differences
International Journal of Antennas and Propagation, 2021 Sources with large power differences are very common, especially in complex electromagnetic environments. Classical DOA estimation methods suffer from performance degradation in terms of resolution when dealing with sources that have large power ...

Invariant Subspace Method and Fractional Modified Kuramoto-Sivashinsky Equation
, 2015 In this paper, the invariant subspace method is applied to the time fractional modified Kuramoto-Sivashinsky partial differential equation. The obtained reduced system of nonlinear ordinary fractional equations is solved by the Laplace transform method and with using of some useful properties of Mittag-Leffler function.

On model reduction for quantum dynamics: symmetries and invariant subspaces
, 2014 Simulation of quantum dynamics is a grand challenge of computational physics. In this work we investigate methods for reducing the demands of such simulation by identifying reduced-order models for dynamics generated by parameterized quantum Hamiltonians.

Localized Basis for Effective Lattice Hamiltonians: Lattice Wannier Functions
, 1995 A systematic method is presented for constructing effective Hamiltonians for general phonon-related structural transitions. The key feature is the application of group theoretical methods to identify the subspace in which the effective Hamiltonian acts ...

Basic principles and aims of model order reduction in compliant mechanisms [PDF]
Mechanical Sciences, 2011 Model order reduction appears to be beneficial for the synthesis and simulation of compliant mechanisms due to computational costs. Model order reduction is an established method in many technical fields for the approximation of large-scale linear time ...

Ibn AL- Haitham Journal For Pure and Applied Sciences, 2020 In this paper, several types of space-time fractional partial differential equations has been solved by using most of special double linear integral transform ”double Sumudu ”. Also, we are going to argue the truth of these solutions by another analytically method “invariant subspace method”.
