There are differences and connections between topics and papers. The subject is to find and solve problems, which is equivalent to doing projects. Papers need to be written and published in appropriate journals. So, what is the connection between the topic and the paper? Mainly reflected in two aspects:

First, topics and papers are both methods to add points to the evaluation of professional titles.

Second, papers are usually the expression of scientific research results.

There are many forms of scientific research results of the subject, and the thesis is one of the common requirements, even for most subjects. It is mandatory that scientific research results without papers cannot be concluded. And the results of papers are often not one, at least two. So there is a great connection between the two.
