I am looking for ways to improve my mathematical French while learning more material about either finite group theory or geometric group theory. In particular, I would love to find a French equivalent to Rotman's group theory book, if possible. As far as geometric group theory goes, I am open to about anything, but I love Cayley graphs and hyperbolic groups. I apologize if this request is too vague, but do any of you have suggestions for French texts in these areas? In terms of mathematical background, I would consider myself a beginner with a decent foundation in these subjects. Thanks in advance!
