Ou Liu (刘欧)

I am a master’s student in Mathematics at the University of Regensburg, with interests in motivic homotopy theory, derived algebraic geometry, and higher category theory. Before Regensburg, I studied at Shanxi University, where my undergraduate thesis applied the six-functor formalism to smooth representation theory.
