On modules arising from quantum groups at $p^{r}$ -th roots of unity

Hankyung Ko

This paper studies the "reduction mod $p$ " method, which constructs large classes of representations for a semisimple algebraic group $G$ from representations for the corresponding…

Cohomology in singular blocks for a quantum group at a root of unity

Hankyung Ko

Let $U_{ζ}$ be a Lusztig quantum enveloping algebra associated to a complex semisimple Lie algebra $g$ and a root of unity $ζ$ . When $L, L^{'}$ are irreducible $U_{ζ}$ -modules ha…
