Element of a list

Context

A term in the theory of lists.

Definition

A list is made up of elements. Thus, for example, a list of numbers has numbers as the elements. For example:

(1,2,4)

is a list with the following elements:

  • 1
  • 2
  • 4

Again, a list can be made up of names. The following list:

[Peter,Paul,Mary,Susan]

has the following elements:

  • Peter
  • Paul
  • Mary
  • Susan

Thus an element in a list is a member of the list.


Embedding

Context

A term in conceptual graph theory (and other domains).

Definition

Generally, if an entity A is embedded within another entity B, then A is situated structurally inside of B. In addition, A is seen as a substructure within B.

In conceptual graph theory, a conceptual graph G can be embedded in the referent of a concept C. For example:

  [Situation:
    [Man]<-(Agnt)<-[Walk]
  ]
  "There is this situation: A man is walking."

In this example, the conceptual graph

  [Man]<-(Agnt)<-[Walk]

is embedded inside the concept with the type "Situation".

Note how the conceptual graph is inside the concept, and note how the conceptual graph is a substructure of the concept.


Entity

Generally speaking, "Entity" is a name we can give to anything at all about which we wish to speak.

In conceptual graph theory, "Entity" is the top-most type in the type hierarchy; it is the one type which is a supertype of everything else. As such, it contrasts with Absurdity.
