- In mathematics, the
infimum (abbreviated inf; pl.: infima) of a
subset S {\displaystyle S} of a
partially ordered set P {\displaystyle P} is the greatest...
- In mathematics, the
concepts of
essential infimum and
essential supremum are
related to the
notions of
infimum and supremum, but
adapted to
measure theory...

fashion for a
function (see
limit of a function). For a set, they are the
infimum and
supremum of the set's
limit points, respectively. In general, when...
-
unique supremum (also
called a
least upper bound or join) and a
unique infimum (also
called a
greatest lower bound or meet). An

given by the...
-
partially ordered set in
which all
subsets have both a
supremum (join) and an
infimum (meet). A
conditionally complete lattice satisfies at
least one of these...
-
bound is said to be a
tight lower bound, a
greatest lower bound, or an
infimum, if no
greater value is a
lower bound. An
upper bound u of a

limit infimum and

sequence always exist and can be used to
determine convergence: the
