Perturbation analysis of a matrix differential equation $\dot x=ABx$ [PDF]
Two complex matrix pairs $(A,B)$ and $(A',B')$ are contragrediently equivalent if there are nonsingular $S$ and $R$ such that $(A',B')=(S^{-1}AR,R^{-1}BS)$. M.I. Garc\'{\i}a-Planas and V.V.

A computational solution for a Matrix Riccati differential equation
This paper is concerned with the solution of the finite time Riccati equation. The solution to the Riccati equation is given in terms of the partition of the transition matrix. Matrix differential equations for the partition of the transition matrix are derived and are solved using computational methods.

Prime decomposition of quadratic matrix polynomials
We study the prime decomposition of a quadratic monic matrix polynomial. From the prime decomposition of a quadratic matrix polynomial, we obtain a formula of the general solution to the corresponding second-order differential equation.

Oscillation of Superlinear Matrix Differential Equations [PDF]
The main purpose of this paper is to extend to matrix differential equations the classic theorem of \textit{F. V. Atkinson} [Pac. J. Math. 5, 643-647 (1955; Zbl 0065.320)], that a necessary and sufficient condition for the solutions of \(y''=f(t)y^{2n+1}\) to be oscillatory is that \(\int^{\infty}_{0}tf(t)dt=\infty\).

Numerical differential continuation approach for systems of nonlinear equations with singular Jacobian [PDF]
It is well known that, one of the useful and rapid methods for a nonlinear system of algebraic equations is Newton’s method. Newton’s method has at least quadratic convergence when the Jacobian is a nonsingular matrix in a neighborhood of the solution ...

Nonlinear Eigenvalue Approach to Differential Riccati Equations for Contraction Analysis [PDF]
In this paper, we extend the eigenvalue method of the algebraic Riccati equation to the differential Riccati equation (DRE) in contraction analysis. One of the main results is showing that solutions to the DRE can be expressed as functions of nonlinear ...

Lax matrix solution of c=1 Conformal Field Theory [PDF]
To a correlation function in a two-dimensional conformal field theory with the central charge $c=1$, we associate a matrix differential equation $\Psi' = L \Psi$, where the Lax matrix $L$ is a matrix square root of the energy-momentum tensor.
