61Empty sum — Not to be confused with Zero sum. In mathematics, an empty sum, or nullary sum, is a summation involving no terms at all. The value of any empty sum of numbers is conventionally taken to be zero. For summations defined in terms of addition of… …
62Exponential sum — In mathematics, an exponential sum may be a finite Fourier series (i.e. a trigonometric polynomial), or other finite sum formed using the exponential function, usually expressed by means of the function:e(x) = exp(2pi ix).Therefore a typical… …
63Sum (monnaie) — Pour les articles homonymes, voir Sum et Soum. Le Sum ou Soum (en ouzbek : Soʻm, ce qui veut dire pur ) est la monnaie de l Ouzbékistan. Son code ISO 4217 est UZS …

65Pandiagonal magic square — A pandiagonal magic square or panmagic square (also diabolic square, diabolical square or diabolical magic square) is a magic square with the additional property that the broken diagonals, i.e. the diagonals that wrap round at the edges of the… …
66Subset sum problem — In computer science, the subset sum problem is an important problem in complexity theory and cryptography. The problem is this: given a set of integers, does the sum of some non empty subset equal exactly zero? For example, given the set { −7, −3 …
67Character sum — In mathematics, a character sum is a sum of values of a Dirichlet character χ modulo N, taken over a given range of values of n. Such sums are basic in a number of questions, for example in the distribution of quadratic residues, and in… …
68Mock modular form — In mathematics, a mock modular form is the holomorphic part of a harmonic weak Maass form, and a mock theta function is essentially a mock modular form of weight 1/2. The first examples of mock theta functions were described by Srinivasa… …
69Construction of t-norms — In mathematics, t norms are a special kind of binary operations on the real unit interval [0, 1]. Various constructions of t norms, either by explicit definition or by transformation from previously known functions, provide a plenitude of… …
70Dedekind sum — In mathematics, Dedekind sums, named after Richard Dedekind, are certain sums of products of a sawtooth function, and are given by a function D of three integer variables. Dedekind introduced them to express the functional equation of the… …
