We can easily establish that f (t) = (1/a)[1 − e−at ]. 42 CHAPTER 2. INVERSION FORMULAE AND PRACTICAL RESULTS Thus lim f (t) = 1/a. t→∞ Application of the theorem gives lim sf¯(s) = lim 1/(s + a) = 1/a, s→0 s→0 which confirms the result obtained previously. Also, applying the initial value theorem gives lim sf¯(s) = lim 1/(s + a) = 0 = f (0), s→∞ s→∞ which confirms the result that lim f (t) = 0. 5 Series and Asymptotic Expansions In the previous section we were interested in estimating the limiting value of f (t), if it existed, as t → 0 and t → ∞.

Thus the function p(x) = {1 + (1/c)(b − x)(x − a)}r , can be made as large as we please in a < x < b and as small as we like in 0 < x < a, b < x < 1 by appropriate choice of r. But p(x) is a polynomial in x, and by our hypothesis 1 xn−1 ψ(x)dx = 0, for n = 1, 2, · · · 0 we should have 1 p(x)ψ(x)dx = 0, 0 for every positive integer r. But the above inequalities imply that, by choosing r large enough, 1 p(x)ψ(x)dx > 0. 0 The first alternative thus leads to a contradiction. A similar argument applies if we assume ψ(x) < 0 in (a,b).

8 Multidimensional Laplace Transforms We have restricted our exposition of Laplace transforms to functions of one variable but we could equally well extend our definition to a function of two or more variables. e. 1, — see Ditkin and Prudnikov [67] for a fuller account of the criteria needed for convergence. We can, as earlier, deduce the Laplace transform for elementary functions of two variables. Useful general results are:1. If f (t1 , t2 ) = f1 (t1 )f2 (t2 ) and L{f1 (t1 )} = f¯1 (s1 ) and L{f2 (t2 )} = f¯2 (s2 ) then L2 {f (t1 , t2 )} = f¯1 (s1 )f¯2 (s2 ).
