Definition
A tuple is a (potentially) mixed type vector of things. However as it may not be in a vector space we do not call it a vector.
Examples
(1,2,3,{a}) is the tuple of the numbers 1, 2 and 3 and the set {a}
Short hands
- Countably infinite tuples
- (an)∞n=1
- (a1,...)(using numbers implies countable)
- (an)∞n=1
- Finite tuples
- (a1,...,an)
- (ai)ni=1
- (a1,...,an)
- Indexed tuples
- (aα)α∈Iwhere I is the indexing set
- (aα)α∈I
