List of things named after Joseph Fourier

This is a list of things named after Joseph Fourier:

Mathematics

Fourier analysis
Fourier series (generalized Fourier series)
- Fourier–Bessel series
- Laplace–Fourier series, see Laplace series
- Legendre–Fourier series, see Laplace 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
  - Fast Fourier transform (FFT), a fast algorithm for computing a Discrete Fourier transform
  - Finite Fourier transform
  - Fractional Fourier transform (FRFT), a linear transformation generalizing the Fourier transform, used in the area of harmonic analysis
- Fourier–Deligne transform
- Fourier–Mukai transform

Fourier's law of heat conduction
Fourier number ( ${\text{Fo}}$ ) (also known as the Fourier modulus), a ratio $\alpha t/d^{2}$ of the rate of heat conduction $\alpha t$ to the rate of thermal energy storage $d^{2}$
Fourier optics
Fourier transform spectroscopy, a measurement technique whereby spectra are collected based on measurements of the temporal coherence of a radiative source
