Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters.
The letter F with hook (uppercase Ƒ, lowercase: ƒ) is a letter of the Latin script, based on the italic form of f; or on its regular form with a descender hook added. A very similar-looking letter, ʄ (a dotless j with a hook and a horizontal stroke), is used in the IPA for a voiced palatal implosive .
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. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
Random variables are usually written in upper case Roman letters, such as or and so on. Random variables, in this context, usually refer to something in words, such as "the height of a subject" for a continuous variable, or "the number of cars in the school car park" for a discrete variable, or "the colour of the next bicycle" for a categorical variable.
In the mathematical discipline of graph theory, a graph labeling is the assignment of labels, traditionally represented by integers, to edges and/or vertices of a graph. [1] Formally, given a graph G = (V, E), a vertex labeling is a function of V to a set of labels; a graph with such a function defined is called a vertex-labeled graph.
Letters with ascenders are b d f h k l. A stroke which drops below the baseline is a descender. [7] Letters with descenders are g j p q y. An arching stroke is a shoulder as in the top of an R or sometimes just an arch, as in h n m. [4] A closed curved stroke is a bowl in b d o p q D O P Q; B has two bowls. A bowl with a flat end as in D P is a ...
The prime symbol is often used to modify notation for graph invariants so that it applies to the line graph instead of the given graph. For instance, α ( G ) is the independence number of a graph; α ′( G ) is the matching number of the graph, which equals the independence number of its line graph.
