Dave Green’s PhD/research antecedents (and Erdős number)


Here is a list of my PhD supervisor, their PhD supervisor... their academic ‘advisor’ (in the days before PhDs)... etc.

Note that the latter (‘advisor’) links are due to Wikipedia, so trust them as much as you want to. But these are also reported by the Mathematics Genealogy Project (MGP). Also there are some additional branches, not shown above, due to multiple ‘advisors’.

In the MGP you can take things back even further. From Isaac Newton to:

For those names in bold above, see here.

Update 2023 June: in addition, a different route, via Ernest Rutherford then Alexander Bickerton, … leads all the way back to Ghiyāth al-Dīn Abū al-Fatḥ ʿUmar ibn Ibrāhīm al-Khayyām al-Nīsābūrī, commonly known as Omar Khayyam. See this .pdf for the route, which also includes the route above, including some of the additional ‘advisor’ branches.

Omar Khayyam is the person in MGP with most descendants, 206459 (as of 2023 June).

Erdős number

My Erdős number is 5 (because, according to the American Mathematical Society’s webform, my PhD supervisor – who I have co-authored many papers with – has an Erdős number of 4). I don’t have a Bacon number.
