I'm looking for modern graduate-level non-English-language differential geometry textbooks. I'm interested in original works by non-English-language speakers in their native languages, not translations into non-English languages. I'm also not interested in non-English language textbooks which are available in English translations, such as Manfredo Perdigão do Carmo's "Riemannian geometry".
I have already made a list of about 45 English-language textbooks, and I have already acquired the following non-English-language DG books.
- Francisco Gómez Ruiz, "Geometría diferencial y geometría de Riemann", 2015.
- Rolf Sulanke, Peter Wintgen, "Differentialgeometrie und Faserbündel", 1972.
- Paul Malliavin, "Géométrie différentielle intrinsèque", 1972.
- Yvonne Choquet-Bruhat, "Géométrie différentielle et systèmes extérieurs", 1968.
Most of these are not recent. On the standard online bookshop web sites, I have only found elementary books on classical non-intrinsic differential geometry in non-English languages. I'm really looking for up-to-date graduate-level books like the Gomez Ruiz book. And by the way, not in CJK languages please. I can struggle through most languages with a dictionary, but Chinese characters are just a bit too much work for me.
My purpose is to include the books in the bibliography of a book I'm writing. I would also like to read them myself!
