I have a question professor, in the textbook [電気情報系の応用数学] page 26 equation (1.100), the f(\omega) can be expressed as an integral with exp(-i\omega x), but in Wikipedia en.wikipedia.org/wiki/Fourier_transform , the Fourier transform is expressed with exp(-2\pi i\omega x), may I ask which one is correct? does that two equation can be converted to each other?

By change of variables, two expressions are essentially equal. For instance, you can see "Units and duality" in the Wikipedia article.
