Poisson summation formula — The Poisson summation formula is an equation relating the coefficients of the Fourier Series of the periodic extension of a function in terms of the values of the function s continuous Fourier transform. The Poisson Summation Formula was… … Wikipedia
Stefan–Boltzmann law — The Stefan–Boltzmann law, also known as Stefan s law, states that the total energy radiated per unit surface area of a black body in unit time (known variously as the black body irradiance, energy flux density, radiant flux, or the emissive… … Wikipedia
Cauchy-Riemann equations — In mathematics, the Cauchy Riemann differential equations in complex analysis, named after Augustin Cauchy and Bernhard Riemann, are two partial differential equations which provide a necessary and sufficient condition for a differentiable… … Wikipedia
Jet (mathematics) — In mathematics, the jet is an operation which takes a differentiable function f and produces a polynomial, the truncated Taylor polynomial of f , at each point of its domain. Although this is the definition of a jet, the theory of jets regards… … Wikipedia
Summation — For evaluation of sums in closed form see evaluating sums. : Summation is also a term used to describe a process in synapse biology. Summation is the addition of a set of numbers; the result is their sum or total . The numbers to be summed may be … Wikipedia
Liouville's theorem (Hamiltonian) — In physics, Liouville s theorem, named after the French mathematician Joseph Liouville, is a key theorem in classical statistical and Hamiltonian mechanics. It asserts that the phase space distribution function is constant along the trajectories… … Wikipedia
LSZ reduction formula — In quantum field theory, the LSZ reduction formula is a method to calculate S matrix elements (the scattering amplitudes) from the time ordered correlation functions of a quantum field theory. It is a step of the path that starts from the… … Wikipedia
Two-state quantum system — In quantum mechanics, a two state system (a.k.a. TLS=Two Level System) is a system which has two possible states. More formally, the Hilbert space of a two state system has two degrees of freedom, so a complete basis spanning the space must… … Wikipedia
