Abstract $2N$ line-soliton solutions of the (2+1)-dimensional Kadomtsev--Petviashvili equation can be presented by resorting to the Hirota bilinear method. By extending the real parameters into complex parameters, this paper obtains $N$ periodic-soliton solutions of the (2+1)-dimensional Kadomtsev--Petviashvili equation from the $2N$ line-soliton solutions.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
