Many types of bracket are used in mathematics. Their meanings depend not only on their shapes, but also on the nature and the arrangement of what is delimited by them, and sometimes what appears between or before them. For this reason, in the entry titles, the symbol is used as a placeholder for schematizing the syntax that underlies the meaning.
Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
Concerning general linear maps, linear endomorphisms, and square matrices have some specific properties that make their study an important part of linear algebra, which is used in many parts of mathematics, including geometric transformations, coordinate changes, quadratic forms, and many other parts of mathematics.
For any pair of morphisms f : B → B′ and h : A′ → A the following diagram commutes: Both paths send g : A → B to f ∘ g ∘ h : A′ → B′. The commutativity of the above diagram implies that Hom(–, –) is a bifunctor from C × C to Set which is contravariant in the first argument and covariant in the second. Equivalently, we ...
(exp x is also written as e x.) expi – cos + i sin function. (Also written as cis.) expm1 – exponential minus 1 function. (Also written as exp1m.) exp1m – exponential minus 1 function. (Also written as expm1.) Ext – Ext functor. ext – exterior. extr – a set of extreme points of a set.
If A ∩ H(u) is a singleton {y}, say, it follows that the support function is differentiable at u and its gradient coincides with y. Conversely, if h A is differentiable at u, then A ∩ H(u) is a singleton. Hence h A is differentiable at all points u ≠ 0 if and only if A is strictly convex (the boundary of A does not contain any line segments).
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.
A statement such as that predicate P is satisfied by arbitrarily large values, can be expressed in more formal notation by ∀x : ∃y ≥ x : P(y). See also frequently. The statement that quantity f(x) depending on x "can be made" arbitrarily large, corresponds to ∀y : ∃x : f(x) ≥ y. arbitrary A shorthand for the universal quantifier. An ...
