    Is it not the case -

    [tex] \int_{-\infty}^\infty}\theta (a)e^{ikx}dx = \int_{a}^{\infty}e^{ikx}dx[/tex]

    what you have written is fourier transforamtion of the "usual" theta function.
    i would like to know how to transform theta function which in arguments have other function s [i.e. functional theta function].
