Please note that my guide abandoned me and I am studying and preparing my masters thesis myself. There is no help from any faculty in my department as they can not bother, as they are not guide. Being enrolled in a 3rd world institute, this is not surprising.
I read 5 research papers (4 are on odd zeta values and 1 on Goldbach Conjecture) in number theory and I will explain the steps involved and prove statements which authors didn't prove. So, my thesis is expository and I have not proved any original results. I have written a rough draft of explanations of the papers.
But I don't know what should I write in the preface or beginning of my thesis, explaining what I have done as I have no idea of these sort of technical language. Also, I searched on internet about expository thesis but most theses were on proving some results or generalizing some conjecture. I could not find a work related to mine. So, I am asking here. I have also to be very cautious so that I am not accused of plagrism.
First 4 papers are about 4 different methods used in studying irrationality of odd zeta values and the 5th paper is a bit different.
Can someone please tell what to write in the preface.
