التعريفات والمعاني
== English ==
=== Etymology ===
Borrowed from Latin supremum.
=== Pronunciation ===
(Received Pronunciation) IPA(key): /səˈpɹiːˌmʌm/
(General American, Canada) IPA(key): /səˈpɹiˌmʌm/
(General Australian, New Zealand) IPA(key): /səˈpɹiːˌmɐm/
=== Noun ===
supremum (plural supremums or suprema)
(set theory) (real analysis): Given a subset X of R, the smallest real number that is ≥ every element of X; (order theory): given a subset X of a partially ordered set P (with partial order ≤), the least element y of P such that every element of X is ≤ y.
Synonyms: least upper bound, LUB, sup
Coordinate term: infimum
==== Usage notes ====
Commonly denoted sup(X).
The supremum of X may not exist, and, if it does, may not be an element of X.
(order theory):
Formally: Let
S
=
{
t
:
t
∈
P
:
∀
x
∈
X
,
x
≤
t
}
{\displaystyle S=\{t:t\in P:\forall x\in X,x\leq t\}}
be the set of upper bounds of X. Then sup(X), if it exists, is the element
s
∈
S
:
∀
y
∈
S
,
s
≤
y
{\displaystyle s\in S:\forall y\in S,s\leq y}
.
The concept of supremum is closely related to the function ∨ (called join). The supremum of two elements, denoted
sup
{
x
,
y
}
{\displaystyle \sup\{x,y\}}
can also be written
x
∨
y
{\displaystyle x\lor y}
. The supremum of a set may be denoted
sup
(
X
)
{\displaystyle \sup(X)}
or
⋁
X
{\displaystyle \bigvee X}
.
