Paul Erdős was a prolific Hungarian mathematician known for his extensive collaboration and contributions across many fields of mathematics, including number theory, combinatorics, and graph theory. He published over 1,500 papers with more than 500 co-authors, making him one of the most collaborative mathematicians in history. This inspired the concept of the Erdős number, which measures the "collaborative distance" between an author and Erdős based on joint publications. Erdős himself has an Erdős number of 0; his direct co-authors have an Erdős number of 1, their co-authors have a number of 2, and so on. The concept highlights the interconnectedness of the mathematical research community. See Jerry Grossman - The Erdős Number Project for more details.
Thanks to my advisors and my mentors and their collaborators, my Erdős number is 3.
My Erdős number is 3, as given by one of following sets of publications:
