- Classical control : Methodologies developed prior to the advent of state space methods, which rely heavily on complex analysis and transform methods, especially the Laplace and Fourier transforms, as well as graphical techniques.
- Convolution (mathematics) : A process which combines two functions on a set to produce another function on the set: the value of the product function depends on a range of values of the argument.
- Distributed computing : A strategy for improving the speed of highly parallelizable tasks by distributing pieces of the problem across many computers that together form a distributed computing system, e.g. BOINC, SETI@home.
- Distribution (mathematics) : Objects which generalize functions, used to formulate generalized solutions of partial differential equations.
- Electromagnetic wave : A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons.
- Fixed point : A point in the domain of a function that is mapped to itself by the function, i.e., a point x such that f(x) = x.
- Helmholtz decomposition : Decomposition of a vector field in a transverse (divergence-free) and a longitudinal (curl-free) component.
- Inhomogeneous Helmholtz equation : An elliptic partial differential equation arising in acoustics and electromagnetism.
- Joseph Fourier : was a French mathematician and physicist credited with describing the Fourier series based on which the Fourier transform has been formed.
- NMR spectroscopy : The use of electromagnetic radiation, in the presence of a magnetic field, to obtain information regarding transitions between different nuclear spin states of the nuclei present in the sample of interest.
- Normal distribution : a symmetrical bell-shaped probability distribution representing the frequency of random variations of a quantity from its mean.
