Instruction for authors

__ The papers should be submitted electronically. Each manuscript should be prepared by using LaTeX with

\documentclass[a4paper,12pt]{article}______(LaTeX 2e)

Do not use any local commands, nor macros.
__ The manuscript should contain the following:

____ 1. Abstract (of approximately 10 lines without mathematical formulas and citation of references)
____ 2. Key Words and Phrases
____ 3. 2020 Mathematics Subject Classification Numbers

These should be put before Introduction, and no footnotes may be added except one acknowledging financial support.
Please avoid writing mathematical formulae inside the text environment in a way that causes excessive spacings between the lines or inappropriate line widths. For example, authors are asked to use mathematical formulae such as $1/2$, $\lim_{n\to\infty}$, $\sum_{n=1}^{\infty}$, unless there is some special reason.
Please also check the style of our bibliography in recent publications. Especially, our format of author names is "the family name, the initial of the first name".
__ The source file and the PDF file of the manuscript should be sent via e-mail to
