Forgot to mention supervisor's name in the thesis(due to pressure) and submitted it and got an A for it. Can I be accused of plagiarism at a later date, if this professor wishes to push it forward? This professor was my thesis advisor or guide.There were some portions of the thesis which we both worked on it and some portion was mine. I missed the acknowledgment section
First of all, the Ph.D candidate is always considered the only author of the thesis and the only one to respond legally in case of plagiarism. Despite all the input introduced by your supervisor along your research, he will never be entitled to accuse you of plagiarism due to the lack of acknowledgements. This is just an impolite thing to do, nothing more.
