Nield-Kuznetsov functions and Laplace transforms of parabolic cylinder functions

T. M. Dunster

Nield-Kuznetsov functions of the first kind are studied, which are solutions of an inhomogeneous parabolic Weber equation, and have applications in fluid flow problems. Connection…

Uniform asymptotic expansions for solutions of the parabolic cylinder and Weber equations

T. M. Dunster

Asymptotic expansions are derived for solutions of the parabolic cylinder and Weber differential equations. In addition the inhomogeneous versions of the equations are considered,…
