Caltech’s official faculty profile identifies this mathematician as Tony Yue Yu, and a Caltech news article about his work does the same. In other words, the post appears to be referring to a real Caltech professor, but gives his name incorrectly.

This is a straightforward name error, not a disputed point:

• Caltech PMA faculty page: “Tony Yue Yu”
• Caltech news article: “New professor of mathematics Tony Yue Yu”

So the text “Tony Yeu Yu” is incorrect; the correct name is Tony Yue Yu.
