Webproblems with homogeneous boundary conditions: u t = ku xx; u(x;0) = f(x); u(a;t) = u(b;t) = 0: Then we’ll consider problems with zero initial conditions but non-zero boundary values. We can add these two kinds of solutions together to get solutions of general problems, where both the initial and boundary values are non-zero.
