What method can I use to find an asymptotic expansion for an integral of the form
\int_a^b g(k)\left[f(k)\right]^tdk
where the domains of the functions are the reals, but mapping onto the complex plane, i.e., f,g:\mathcal{R}\to\mathcal{C}. Can I use Laplace's method, stationary phase method, steepest descent, etc? Is there any other option?
Thanks in advance!!!
