Analysis

• Fourier analysis
• Fourier series
  • Fourier–Bessel series

  • Generalized Fourier series
  • Laplace–Fourier series, see Laplace series
  • Fourier–Legendre series
• Fourier transform ( List of Fourier-related transforms):
  • • Discrete-time Fourier transform (DTFT), the reverse of the Fourier series, a special case of the Z-transform around the unit circle in the complex plane
    • Discrete Fourier transform (DFT), occasionally called the finite Fourier transform, the Fourier transform of a discrete periodic sequence (yielding discrete periodic frequencies), which can also be thought of as the DTFT of a finite-length sequence evaluated at discrete frequencies

In physics and engineering

• Fourier's law of heat conduction

• Fourier optics
• Fourier-transform spectroscopy, a measurement technique whereby spectra are collected based on measurements of the temporal coherence of a radiative source
