Consider diffusion inside an enclosed circular tube. let its length (circumference) be 2l. let x denote the arc length parameter where −l ≤ x ≤ l. then the concentration of the diffusing substance satisfies ut = kuxx for − l ≤ x ≤ l u(−l, t) = u(l, t) and ux (−l, t) = ux (l, t). these are called periodic boundary conditions. (a) show that the eigenvalues are λ = (nπ/l) 2 for n = 0, 1, 2, . (b) show that the concentration is u(x, t) = 1 2 a0 +[infinity] n=1 an cos nπx l + bn sin nπx l e−n2π2kt/l 2 .
