Author Guidelines

Authors should submit their manuscripts electronically mail in the form of .pdf file via our online submission system. (New registaration is required. Your password will be sent automatically to your provided email.) The manuscript should be prepared only using LaTeX with THAIJMATHsty (thaijmath.cls here) and the number of pages should not exceed 20. Only papers submitted in English will be considered for publication. The submission of a paper implies that the paper is not being considered for publication by other journals. After the manuscript is accepted, authors must send the Latex file of the final version via the online system and the authors will be requested to transfer copyright the publisher via The manuscript must be typed on one side of the paper preferably by LaTeX or AMS tex.

The abstract must not exceed 200 words. Leave two lines between the address(es) and abstract.

Mathematics Subject Classification (MSC): You may find MSC here.
Key Words: Put at least 3 key words (or phrases).

Please ensure that every reference given in the reference list must also be cited in the text. The references will be cited sequentially in the text. Unpublished results is not recommended in the reference list. The following reference styles should be used:

D. Gopal, P. Kumam, M. Abbas, Background and Recent Developments of Metric Fixed Point Theory, CRC Press; Taylor & Francis Group LLC, New York, 2017.

R.T. Rockafellar, On the maximal monotonicity of subdifferential mappings mappings, Pacific J. Math. 33 (1970) 209-216.

S. Suantai, Matrix transformation of some vector valued sequence spaces, Lecture Note in Pure and Applied Mathematics, Marcel Dekker, New York - Basel (2000), 489-495.

Any references cited in the abstract must be given in full. References should be cited in the text as, e.g., [5], [6, p. 213], or [6, Theorem 2.1]. It is suggested that the theorem and page numbers be used for referencing instead of just a number representing an entire book or paper, and also that only those papers or books which are actually cited in the text be listed as references.
