When reading, you will have some doubts about the contents of the paper because it conflicts with common knowledge. Or, you might think it is difficult to understand the story. I would greatly appreciate it if you let me know your comments and criticisms.

I am afraid that I might not be able to reply to your comments and criticisms, but I will refer to them when I upload the revised version.

When you send your comments or criticisms, please click "Comments and criticis" below. It shows my e-mail address.

It is, of course, all right for you to remain anonymous. If you do not care, please let me know your e-mail address.
