I am currently researching the foundations of graph theory (math). I have noticed two kind of things in introduction books.
- There are results seemingly so obvious nobody writes about it.
- There are variants of the topic mentioned in almost any book, but covered in detail in none.
At the time of writing this question, the stack exchange community was unable to help me with my observations in my specific case. Since I think very highly of this network, I'm starting to believe that currently there are no suitable books about these topics.
But I feel like there ought to be books about it. The question is, what do I do in this situation? How can I "help" that such a book gets written? The most obvious answer would be "Write the book.". Although I like the approach, this is not possible. For simplicity's sake let's just say I lack the time. So what to do? Like, can I just mail a publisher "Why don't you already have this kind of book?", although I don't know anyone working at any publisher? Do I ask a professor at my university if (s)he would like to write one? Btw I'm a graduate student, but I don't think it is relevant for the question.
Please note this question is not about how I can research a certain topic. It is really about how books of some topic do not exist. Please assume for answering that they don't. If you happen to know about books about the exemplary example topic I provided here, please answer in my linked question, not here.
