A sphere in 3-space (also called a 2-sphere because it is a 2-dimensional object) consists of the set of all points in 3-space at a fixed distance r from a central point P. The solid enclosed by the sphere is called a ball (or, more precisely a 3-ball). The volume of the ball is given by
The subset of the integers {0,1,2} is contained in the interval of real numbers [0,2], which is convex. The Shapley–Folkman lemma implies that every point in [0,2] is the sum of an integer from {0,1} and a real number from [0,1]. [7] The distance between the convex interval [0,2] and the non-convex set {0,1,2} equals one-half:
The Volterra series is a model for non-linear behavior similar to the Taylor series.It differs from the Taylor series in its ability to capture "memory" effects. The Taylor series can be used for approximating the response of a nonlinear system to a given input if the output of the system depends strictly on the input at that particular time.
[3] [4] The boundary conditions are usually imposed by the Simultaneous-Approximation-Term (SAT) technique. [5] The combination of SBP-SAT is a powerful framework for boundary treatment. The method is preferred for well-proven stability for long-time simulation, and high order of accuracy.
A continuous-time Markov chain (X t) t ≥ 0 is defined by a finite or countable state space S, a transition rate matrix Q with dimensions equal to that of the state space and initial probability distribution defined on the state space.

where the positive constants C and r can be determined by the requirements that the sum of all the probabilities must be 1 and the expected value must be μ. For example, if a large number N of dice are thrown, and you are told that the sum of all the shown numbers is S .
