As a special event, I share my experience and rules of thumb on writing a good thesis. Here "good" is irrelevant to mathematical contents, but means precise words, simple sentences, and plain styles. I focus on the following aspects with my draft of thesis as concrete examples of illustration:

 

1. How to set up a plan of writing?

2. How to structure subsections, sections, and chapters?

3. How to use the three books?

 

i. On Writing Well (author: William, Zinsser)

ii. SIAM Style Manuel
