Hyperterminants II

Hyperasymptotic expansions are in terms of certain multiple integrals, the so-called hyperterminants. This paper deals with the hyperterminants that are needed in the hyperasymptotic expansions of higher-order linear differential equations, nonlinear differential equations and integrals with saddles. We give new integral representations for the hyperterminants. With these integral representations we are able to obtain convergent and computable series expansions for the hyperterminants.
