I can't find a book named that by him.
user
Oh! I’m sorry, I meant “La Théorie des Groupes de Lie”.
assistant
I think you are mistaken.
user
No, that’s exactly the book I was referring to.  The title means “The Theory of Lie Groups” in French, and it was published in 1965.  I hope you find it helpful!
