My Erdos Number

My Erdos number is at most 5:

At least according to Dave Clarke who wrote “My Erdos number is 5 (Clarke, Jay, Moggi, Longo, Csiszar, Erdos).”. (But DBLP does not confirm the link Clarke/Jay nor the link Longo/Csiszar.)

Dave writes: For the record, the Longo/Csiszar connection can be found on Erdos2. I can confirm the Clarke/Jay paper: Exploiting Shape in Parallel Programming. C B Jay, D Clarke, J Edwards.

Root: Shela (6)

My Erdos number is at most 6:

According to the Erdos2 list

  • Erdos (0)
  • Saharon Shela (1)
  • Amir Pnueli (2)

According to DBLP

Here is a part of the search tree

  • SHELAH, SAHARON (1)
  • Pnueli, Amir (2)
    • Willem P. de Roever (3)
    • Krzysztof R. Apt (3)
      • Jan Bergstra (4)
        • Paul Klint (5)
          • Eelco Visser (6)
      • Jacob Brunekreef (4)
        • Sjouke Mauw (5)
          • Wilco Koorn (6)
      • Gordon D. Plotkin (4)
        • Rob J. van Glabbeek (5)
          • Wan Fokkink (6)
            • S. P. Luttik (7)
              • Eelco Visser (8)

Root: Ullman (7)

Computer scientists should really refer to their Ullman number. Mine is

  1. This is the first Erdos link that I found quite quickly with the help of DBPL.

According to the Erdos2 list

According to DBLP

Root: Salomaa

Another path might exist through Arto Salomaa (2) but I haven’t found it yet.

Conclusion

(1) The length 6 and 7 paths are completely disjoint and correspond to algebraic and strategic periods, respectively.

(2) It is surprising (or maybe not) how people with offices next to each other don’t write papers together. Should do that more often.
