Manche Symbole sind in jedem LaTeX-2ε-System verfügbar; andere benötigen zusätzliche Schriftarten oder Pakete, die nicht notwendig in jeder Distribution mitgeliefert werden und daher selbst installiert werden müssen.
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 letters in various fonts often have specific, fixed meanings in particular areas of mathematics.

The template attempts to use any calligraphic font that may be installed on several operating systems, either as default or as part of an office package. The fonts called are: Lucida Calligraphy, Monotype Corsiva, URW Chancery L, Apple Chancery, and Tex Gyre Chorus. Failing all these, the generic font families cursive and serif are used.
In mathematics (specifically linear algebra, operator theory, and functional analysis) as well as physics, a linear operator acting on an inner product space is called positive-semidefinite (or non-negative) if, for every (), , and , , where is the domain of .
Cursive is a style of penmanship in which the symbols of the language are written in a conjoined, or flowing, manner, generally for the purpose of making writing faster.. This writing style is distinct from "print-script" using block letters, in which the letters of a word are unconnect
One can define positive-definite functions on any locally compact abelian topological group; Bochner's theorem extends to this context. Positive-definite functions on groups occur naturally in the representation theory of groups on Hilbert spaces (i.e. the theory of unitary representations).
It represents a specialized cursive type of the letter d, just as the integral sign originates as a specialized type of a long s (first used in print by Leibniz in 1686). Use of the symbol was discontinued by Legendre, but it was taken up again by Carl Gustav Jacob Jacobi in 1841, [4] whose usage became widely adopted. [5]
