I am writing my master's thesis and my advisor is taking the total hands-off approach (I am mentioning that because I am still waiting to hear his feedback on the work when he reads it). He wants me to submit the thesis and defend it as soon as possible because there is a deadline for the master's program.
Q1: If I defend my thesis first, can I extract articles from it to be submitted to top math journals?
Q2: I have an idea that is an extension of one of the chapters in my thesis, and planning to work on it for a few months after my defense. Can I use multiple background sections from my master's thesis to be included in the second paper I wish to submit?
How can I ensure that my master's thesis will not be stolen in whole or in part after submitting it to my university/reading (or thesis) committee? - I may seem skeptical but, I live in a country where there are lots of people who may steal each other's work in whole or in part.
