Mapping class groups and their representations


Putman: Introduction to mapping class groups on the Putman-Wieland conjecture and its relation to the Ivanov conjecture (any finite index subgroup of the mapping class group has finite abelianization).
Hadari: On the conjecture of Mc-Mullen: Any pseudo-anosov acts with infinite order on some covering of the original surface.
Venkataramana: Arithmeticity of some Burau representations of the braid groups.
Costantino: Introduction to quantum representations of mapping class groups.
