    On the Gradient Flow Formulation of the Lohe Matrix Model with High-Order Polynomial Couplings

    We present a first-order aggregation model for a homogeneous Lohe matrix ensemble with higher order couplings via a gradient flow approach. For homogeneous free flow with the same Hamiltonian, it is well known...
