Research Interest: P-adic Langlands program, including p-adic and mod p local-global compatibility, and the theory of (higher) L-invariants.

8. Higher L-invariants and Drinfeld's symmetric space, in preparation (joint with Benchao Su and Arnaud Vanhaecke)

We compare Breuil-Schraen L invariants (in higher Ext between locally analytic generalized Steinberg, defined in 7 above) and Fontaine-Mazur L invariants inside the pro etale complex of the Drinfeld symmetric space. In particular, we confirm several conjectures/expectations in 7.

9. On a mixed BGG complex in the Steinberg case, in preparation (joint with Yiqin He)

We construct a complex of finite length admissible locally analytic representations which looks like successive extension of BGG complex for different smooth generalized Steinberg.
