## giga-

$\mathrm G$

The Système Internationale d'Unités metric scaling prefix denoting $10^{\, 9 }$.

Its $\LaTeX$ code is \mathrm {G} .

## Group

$G$

Used to denote a general group.

In this context, frequently seen in the compound symbol $\struct {G, \circ}$ where $\circ$ represents an arbitrary binary operation.

The $\LaTeX$ code for $\struct {G, \circ}$ is \struct {G, \circ} .

## Function

$\map g x$

The letter $g$, along with $f$ and $h$, is frequently used to denote a general mapping or function.

The $\LaTeX$ code for $\map {g} {x}$ is \map {g} {x} .

## Geometric Distribution

$X \sim \Geometric p$

$X$ has the geometric distribution with parameter $p$.

The $\LaTeX$ code for $X \sim \Geometric {p}$ is X \sim \Geometric {p} .

## Shifted Geometric Distribution

$X \sim \ShiftedGeometric p$

$X$ has the shifted geometric distribution with parameter $p$.

The $\LaTeX$ code for $X \sim \ShiftedGeometric {p}$ is X \sim \ShiftedGeometric {p} .

## Generating Function

$\map {G_A} z$

Let $A = \left \langle {a_n}\right \rangle$ be a sequence in $\R$.

Then $\displaystyle G_A \left({z}\right) = \sum_{n \mathop \ge 0} a_n z^n$ is called the generating function for the sequence $A$.

The $\LaTeX$ code for $\map {G_A} z$ is \map {G_A} z .

## Acceleration Due to Gravity at the Earth's Surface

$g$

The force exerted on a body at (or near) the surface of the Earth under the influence of the gravitational field given rise to by the Earth.
