## Two main subject naming conventions

There is actually some competition between the names "discrete mathematics" and "combinatorics" for largely overlapping fields. This is reflected in names of textbooks and academic curricula worldwide. The proponents of the term "discrete mathematics" often tend to consider "combinatorics" as the proper name of the subfield which 'the other side' would call "enumerative combinatorics".

As an example: The article Discrete mathematics presently begins

Discrete mathematics, also called finite mathematics, is the study of mathematical structures that are fundamentally discrete

and later defines "combinatorics" as "a study of counting".

Similarly, the article Combinatorics begins:

Combinatorics is a branch of pure mathematics concerning the study of discrete (and usually finite) objects.

This article doesn't mention "discrete mathematics" at all, as far as I can see. ("The word "discrete" supra is linked to Countable set.)

Both articles claim that Graph theory is one of the subfields of its respective subject; and you may note that right now the Category:Graph theory is included as a direct subcategory of both

This is no great matter; I know of no serious disagreements between combinatorists and/or "discrete mathematicians" over this. However, I think our articles should recognise and pinpoint the existence of somewhat different conventions. This could benefit wp readers, who meet the therms with slightly different meanings in different contexts. There might also be an idea to merge the pages Discrete mathematics and Combinatorics -- provided the merged article has the correct title, whatever that is:-). There may also be reasons against; some people tend to include subjects like the full theory of finite groups into "Discrete mathematics", but very few would include it in "Combinatorics", I think.

I would suggest that combinatorics is a subfield of discrete mathematics. Discrete mathematics includes logic and fields related to computing which are not part of combinatorics. Graph theory is also split as a result of this -- computer scientists pay particular attention to algorithmic graph theory, which is of less interest to combinatorists.

I see no benefit in trying to merge combinatorics and discrete mathematics. Radagast3 (talk) 08:30, 14 August 2009 (UTC)

## Rename proposal defeated, three "Outline of" titles restored

Due to a number of undiscussed moves, a proposal was made to rename outlines to "List of ... topics".

The proposal failed.

Therefore, based on the outcome of that discussion (which lasted from Sept 6 to Oct 12), I'm restoring the title of this article to "Outline of discrete mathematics". I have waited for that discussion to be completed to revert the undiscussed move of this page that occurred on Sept 6th.

Note that this article has been named "Outline of discrete mathematics" since June 11, 2009, having been renamed from "Topical outline of discrete mathematics" which it was named since January 8, 2009. All the articles named "Topical outline of" were renamed from "List of basic ... topics" on January 8, 2009 or thereabouts. The entire basic topics department was renamed at that time because the lists had grown beyond the scope of "basic".

Recently, there were a number of mathematics-related lists renamed to outlines by a new editor who rampaged through several departments. Outline of discrete mathematics was not one of them. See Wikipedia talk:WikiProject Mathematics/Archive/2011/Sep#Undiscussed List -> Outline moves.

Apparently during the repair of that mass move, 3 outlines were named to "List of" that were not part of the mass move. This outline was one of the 3.

## Quick explanation of Wikipedia outlines

"Outline" is short for "hierarchical outline". There are two types of outlines: sentence outlines (like those you made in school to plan a paper), and topic outlines (like the topical synopses that professors hand out at the beginning of a college course). Outlines on Wikipedia are primarily topic outlines that serve 2 main purposes: they provide taxonomical classification of subjects showing what topics belong to a subject and how they are related to each other (via their placement in the tree structure), and as subject-based tables of contents linked to topics in the encyclopedia. The hierarchy is maintained through the use of heading levels and indented bullets. See Wikipedia:Outlines for a more in-depth explanation. The Transhumanist 00:05, 9 August 2015 (UTC)
