This is a listing of common symbols found within all branches of mathematics. Each symbol is listed in both HTML, which depends on appropriate fonts to be installed, and in TeX, as an image.
then
ℤ^{+} or ℤ^{>} means {1, 2, 3, ...} . ℤ^{≥} means {0, 1, 2, 3, ...} .
Then [2] = {…, −8, −3, 2, 7, …}.
(Note that the notation (a,b) is ambiguous: it could be an ordered pair or an open interval. Set theorists and computer scientists often use angle brackets ⟨ ⟩ instead of parentheses.)
(a, b, c) is an ordered triple (or 3tuple).
( ) is the empty tuple (or 0tuple).
(Note that the notation (a,b) is ambiguous: it could be an ordered pair or an open interval. The notation ]a,b[ can be used instead.)
(0, +∞) equals the set of positive real numbers.
we can define the structure functions S_{q}(τ):
Note that the notation ⟨u, v⟩ may be ambiguous: it could mean the inner product or the linear span.
The span of S may also be written as Sp(S).
(The notation (a,b) is often used as well.)
is an ordered triple (or 3tuple).
is the empty tuple (or 0tuple).
The contour integral can also frequently be found with a subscript capital letter C, ∮_{C}, denoting that a closed loop integral is, in fact, around a contour C, or sometimes dually appropriately, a circle C. In representations of Gauss's Law, a subscript capital S, ∮_{S}, is used to denote that the integration is over a closed surface.
