WebIn physics many problems arise in the form of boundary value problems involving second order ordinary diﬀerential equations. For example, we might want to solve the equation a 2(x)y′′ +a 1(x)y′ +a 0(x)y = f(x) (6.1) subject to boundary conditions. We can write such an equation in operator form by deﬁning the diﬀerential operator L ... http://people.uncw.edu/hermanr/pde1/pdebook/green.pdf
