Paul Erdos という偉い数学者がいて, 世界中を放浪しながら大勢の数学者と共同研究し、 1000編以上の論文を残しました. そこで, Erdos 自身のErdos番号を 0, Erdosと連名の 論文がある人のErdos番号を 1, Erdos番号1ではないが, Erdos番号1の人と連名の論文が ある人のErdos番号は2, 等々としたものを Erdos 番号と言います。
ここではご親切にもあなたのErdos番号を調べて教えてくれます
Dear Sir,
I would like to know my Erdos number.
I have published in such journals as
Linear Algebra and its Applications with D. G. Luenberger
Journal of Optimization Theory and Applications with D. G. Luenberger
IEEE Trans. on Automatic Control with D. G. Luenberger

Your coauthor Foulds is on the Erdos-2 list on the Web site, so your
number is 3. Here is a path:
