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.

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

On the Invariant Subspace Method for Nonlinear Second-Order Evolution Equations
MathematicsWe investigate invariant finite-dimensional linear spaces for a class of nonlinear evolution equations with second-order time dependence of the type ∂ttu=−∂x(A(x,u)u)+∂xx(B(x,u)u)+f(u), where the coefficients may depend nonlinearly on the solution. Using
