Shared publicly -**The thesis of Madame Sinh**

The thesis of Hoàng Xuân Sính [1], one of Grothendieck's PhD students, dealt with what we call today

**2-groups**, called by her

**gr-categories**. Her thesis is somewhat legendary, being a source of many results, but essentially unavailable to consult. But today I found someone has put it online! (It is hand-written :-)

She received the Ordre des Palmes Académiques [2] for her contribution to the development and scientific cooperation between France and Vietnam.
