Fourier Transform and Differential Equations

  • B. Malgrange
Chapter
Part of the Mathematical Physics Studies book series (MPST, volume 12)

Summary

We study, in the complex domain, the action of the Fourier transform on the solutions of ordinary linear differential equations with polynomial coefficients. In the classical “Laplace method”, there are some restrictions; also, some choice of integration contours seem rather unsystematic. We show how to remove these restrictions and how to make these choices in a more systematic way.
