Systems of linear differential equations with constant coefficients, Ax = x-dot, with the matrix A having nonnegative off-diagonal elements and zero column sums occur in compartmental analysis. The steady-state solution leads to the homogeneous system of linear equations Ax(infinity) = x-dot(...

1、Sec. 4 Solution to Systems of Linear Equations,1 Homogeneous Systems of Linear Equations,2 Non-homogenous Systems of Linear Equations,In this section, we will mainly discuss the following questions,Under what conditions does a system of linear equations have solutions,If a linear system have ...
A zero vector is always a solution to anyhomogeneous system of linear equations. For example, (x, y) = (0, 0) is a solution of the homogeneous system x + y = 0, 2x - y = 0. Sometimes, a homogeneous system has non-zero vectors also to be solutions, To find them, we have to...
power series of inverse matrix of operator polynomial matrix can be found using synthetic division of ascending power of polynomial and polynamial matrix,based on which,a new method of finding a particular solution to nonhomogeneous linear differential equations with constant coeffients can be ...
Answer to: Find the solution of the homogeneous linear system of ODEs X' = AX where A = \begin{bmatrix} 1 & -2 & 2\\ -2 &1 & 2\\ 2 & 2 & 1...
Check that {eq}\displaystyle y_1 = x {/eq} is a solution of the homogeneous equation for the DE {eq}\displaystyle x^2y'' + xy' - y = \frac{4}{x^2} {/eq}.Linear Differential Equation:There are two types of linear differential equations, non-homogen...
Mellin–Barnes representations of Feynman diagrams, linear systems of differential equations, and polynomial solution We argue that the Mellin–Barnes representations of Feynman diagrams can be used for obtaining linear systems of homogeneous differential equations for the...

For us the main interest is the “shape” of the solution sets, just like in the following basic result of linear algebra: solution sets of systems of homogeneous linear equations in n variables over a field K are precisely the subspaces of the vector space Kn, i.e., sets of n-tuples...
ON THE FINDING OF SOLUTIONS FOR SEVERAL CLASSES OF HIGHER ORDER LINEAR DIFFERENTIAL EQUATIONS WITH VARIABLE COEFFICIENTS In §1, two methods for solving the second order homogeneous linear ordinary differential equation with variable coefficients are given, which are different from the one in [4].In...
