As far as the abstract presents our current work, references are not required. I saw little articles with references in the abstract. what do you think about?
By The way It is important that your abstract not contain mathematical notation that may be difficult to properly present in Web browsers. The abstract is not only a part of the full article (print and online) but, more importantly, serves as the only free-to-all record of your paper. It is reused and remapped by a variety of online portals and metadata databases, some of which are text only. Please provide a text-only abstract, or, if that is absolutely impossible, try to minimize the use of math symbols, and please completely avoid accented variables.
Let "abstract" remain "abstract" as the short summary of an article that should contain no reference(s) because the readability of the article won't be affected
It is not entirely unreasonable to include a citation in an abstract, if the reason you are citing it is because your paper is a major extension, rebuttal, or counterpoint to the cited article.
Large numbers of citations, however, should be avoided, as should "secondary" citations. Only the most critical literature for a paper should be cited, and that should normally be limited to one or two. Any more than that, and the abstract becomes hard to read.
Moreover, as the abstract is intended to be an interesting summary of the research described in the manuscript, it is not probably useful to include citations. An exception is the case when a manuscript heavily draws on a previous work. For instance, if you are replicating a previous study, then you may have to include a cite. In this paper, the author replicates and extends a study. The title and the abstract have a citation of the previous study.
An abstract for a paper must be stand-alone, because the bibliography is hidden in the paper itself. The abstract must contain all information required for people to judge if they want to read the paper, and as there is no bibliography, the reader does not know what the citations relate to. Therefore, there should be no citations.
It may be a bit different if the abstract is for a conference. Maybe in some situations it's possible to add one or two references at the end of the abstract. In that case, it can be okay to have citations
The most important question here is: can the reader use the abstract as a stand-alone unit? If using citations cause the answer to this question to be no, don't do citations.
Ok DR Asad It is INFORMS’ style not to cite references in the abstract of a paper. In those rare instances in which an author believes that he or she must cite a reference source in an abstract, the entire reference must be written parenthetically.
