Error Bounds for Asymptotic Expansions of Laplace Convolutions
Received by the editors March 22, 1993; accepted for publication (in revised form) August 10, 1993.
Asymptotic expansions are derived for the Laplace convolution (f*g)(x) as x → ∞, where f and g have asymptotic power series representation in descending powers of t. Bounds are also constructed for the error terms associated with these expansions. Similar results are given for the convolution integrals


as x → ∞. These results can be used in the study of asymptotic solutions to the renewal equation and the Wiener-Hopf equations.
