A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
Card(X) is also written #X, ♯X or |X|.) cas – cos + sin function. cdf – cumulative distribution function. c.f. – cumulative frequency. c.c. – complex conjugate. char – characteristic of a ring. Chi – hyperbolic cosine integral function. Ci – cosine integral function. cis – cos + i sin function. (Also written as expi.) Cl ...
If an airplane's altitude at time t is a(t), and the air pressure at altitude x is p(x), then (p ∘ a)(t) is the pressure around the plane at time t. Function defined on finite sets which change the order of their elements such as permutations can be composed on the same set, this being composition of permutations.
The Heaviside step function, or the unit step function, usually denoted by H or θ (but sometimes u, 1 or 𝟙), is a step function named after Oliver Heaviside, the value of which is zero for negative arguments and one for positive arguments. Different conventions concerning the value H(0) are in use.
Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles.
The potential of a set owned by Maker is 1. Then, Maker wins iff the potential-sum is more than 0, and Breaker wins iff the potential-sum is less than 1. Hence: If the initial sum is more than 0, and Maker can play such that the potential-sum weakly increases, then this is a winning strategy for Maker;
GameMaker (originally Animo, Game Maker (until 2011) and GameMaker Studio) is a series of cross-platform game engines created by Mark Overmars in 1999 and developed by YoYo Games since 2007. The latest iteration of GameMaker was released in 2022.
A homomorphism between two algebras A and B is a function h : A → B from the set A to the set B such that, for every operation f A of A and corresponding f B of B (of arity, say, n), h(f A (x 1, ..., x n)) = f B (h(x 1), ..., h(x n)). (Sometimes the subscripts on f are taken off when it is clear from context which algebra the function is from.)
