Universality of the Galois action on the fundamental group of $P^{1} ∖ {0, 1, \infty}$

Alexander Petrov

We prove that any semi-simple representation of the Galois group of a number field coming from geometry appears as a subquotient of the ring of regular functions on the pro-algebra…

Hodge numbers are not derived invariants in positive characteristic

Nicolas Addington, Daniel Bragg

We study a pair of Calabi-Yau threefolds X and M, fibered in non-principally polarized Abelian surfaces and their duals, and an equivalence D^b(X) = D^b(M), building on work of Gro…
