Thai Journal of Mathematics (TJM) is a peer-reviewed, open access international journal publishing original research works of high standard in all areas of pure and applied mathematics.
Publication Frequency
TJM publishes one volume per year. Usually a volume consists of three issues with about 200 pages each.
Appear : April, August and December. Occasionally special issues are also published. Papers are published as soon as they are accepted.
From 2020 the journal is published every three months and four issues per year (March, June, September and December). All manuscripts are refereed under the same standards as those used by the finest-quality printed mathematical journals.  Accepted papers will be published online in their final form as a TJM formatted PDF and will be published in four issues annually.

The SJR indicator measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is. Cites per Doc. (2y) measures the scientific impact of an average article published in the journal, it is computed using the same formula that journal impact factor ™ (Thomson Reuters).
