Sufficiently large

In mathematics, the phrase sufficiently large is used in contexts such as:

$P$ is true for sufficiently large $x$

which is actually shorthand for:

$\exists~ a\in\mathbb{R}$ such that $P$ is true $\forall~ x\ge a$ .

This does not necessarily mean that any particular value for $a$ is known, but only that such an $a$ exists. The phrase "sufficiently large" should not be confused with the phrases "arbitrarily large" or "infinitely large".

Other uses in mathematics

A sufficiently large manifold is a manifold containing a properly embedded 2-sided incompressible surface.
