A student working on a master thesis in mathematics will have to present it at the end of the semester in front of the professor.
The professor will ask several questions during the presentation, what is the intend of those questions?
Basically, what is the professor trying to achieve through those questions?
Does he want to see whether you are the writer of this thesis and that you didn't have someone else do it for you?
Does he want to know whether you understand the concepts you are presenting? ( I am guessing yes, since this is the point of a master thesis after all)
Does he want to know whether you can use the information in your thesis to come up with other conclusions, not mentioned in the paper? Perhaps give you some short mathematics exercises he expects you to solve during the presentation.
Can you explain what is the point of those questions?
