111Maximum sustainable yield — In population ecology and economics, maximum sustainable yield or MSY is, theoretically, the largest yield (or catch) that can be taken from a species stock over an indefinite period. Fundamental to the notion of sustainable harvest, the concept… …
112Lotka–Volterra equation — The Lotka–Volterra equations, also known as the predator prey equations , are a pair of first order, non linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator… …
113Clenshaw–Curtis quadrature — and Fejér quadrature are methods for numerical integration, or quadrature , that are based on an expansion of the integrand in terms of Chebyshev polynomials. Equivalently, they employ a change of variables x = cos θ and use a discrete… …

115Coherent states — In quantum mechanics a coherent state is a specific kind of quantum state of the quantum harmonic oscillator whose dynamics most closely resembles the oscillating behaviour of a classical harmonic oscillator. It was the first example of quantum… …
116Delta potential — The delta potential is a potential that gives rise to many interesting results in quantum mechanics. It consists of a time independent Schrödinger equation for a particle in a potential well defined by a Dirac delta function in one dimension. For …
