What was the last mathematical paper published in Latin? From an answer to a previous question I learned that Peano published in Latin as long as 1889. > What was the last mathematical paper/book of recognized importance published in Latin?

Zentralblatt lets you search by language of paper where I discovered this recent example.

> **Schechtman, Vadim** _New definition of a vertex algebroid. (Definitio nova algebroidis verticiani.)_ (Latin) A Bernstein, Joseph (ed.) et al., Studies in Lie theory. Dedicated to A. Joseph on his sixtieth birthday. Basel: Birkhäuser. Progress in Mathematics 243, 443-494 (2006).

In the preface, the editors note that Schechtman's paper is "linguistically refreshing"!
