Abstract
For b is an element of R(+), a real function h(x) and also complex ps eudo-functions f(x) and K(x,u) obeying weak assumptions, an asymptotic expansion of the general integral I(lambda):=fp integral(0)(b) f(x)K[ h(x),lambda x]dx, is proposed, with respect to the real and large para meter lambda, where the notation fp designates an integration in the f inite part sense of Hadamard.
