What is an antichain?
An antichain is a subset of a partially ordered set such that any two elements in the subset are incomparable.
What is a set of ordered pairs is called an?
A set of ordered pairs is called a relation. In mathematics, a relation defines a relationship between elements of two sets, where each element from the first set is associated with one or more elements in the second set through ordered pairs. For example, if we have a set of ordered pairs like {(1, 2), (3, 4)}, it represents a specific relation between the first elements and the second elements of those pairs.
What are the first numbers in an ordered pair?
They are the elements from the first set in the original Carestian product. For example, if you make ordered pairs on an x-y plane, then they are the elements of the set X.
A set of two elements in which the order is specified?
It is called an ordered pair.
What is a ordered set of numbers or objects?
An ordered set of numbers or objects is a collection in which the arrangement or sequence of the elements matters. Each item in the set is positioned based on a specific criterion, such as numerical value or alphabetical order. Unlike a regular set, where the order is irrelevant, the order in an ordered set is essential for defining relationships and properties among the elements. Examples include sequences, tuples, and lists.

State the principal of duality in boolean algebra?
If {X,R} is a Partially Ordered Set, then {X,R(inverse)} is also a Partially Ordered Set.

What are the set of ordered pairs for y equals 0.1 x plus 1?
They are elements of the infinite set of ordered pairs of the form (x, 0.1x+1). It is an infinite set and I am not stupid enough to try to list its elements!
What does join mean in maths?
A join and meet are binary operations on the elements of a POSET, or partially ordered set. A join on a set is defined as the supremum with respect to a partial order on the set, provided it exists. A meet on a set is defined either as the unique infimum with respect to the partial order imposed on the set, if the infimum exists.
A set of two elements in which the order is specified?
It is called an ordered pair.
What is the set of the first numbers of the ordered pairs in a relation called?
they are the first set of paired elements
What is the set of first elements in ordered pair or table?
The set of first elements in an ordered pair or table refers to the collection of all the first components from each pair or row. For example, in a set of ordered pairs like {(1, 2), (3, 4), (5, 6)}, the set of first elements would be {1, 3, 5}. This set can also be viewed as the projection of the ordered pairs onto the first coordinate. It provides a way to analyze or categorize the primary values in the given data structure.

Why duplicate tuples are not allowed in DBMS?
Since relation is a set, and tuples are element of a set, according to set theory, the elements of a set are not ordered.
What is the meaning of AxB as applied to set theory?
it denotes the set of ordered pairs with elements of A and b in the format (a,b)
