I’ll discuss some explicit examples of Calabi-Yau threefolds (CY3s) with torsion in various cohomology groups and consequences of such torsion; in particular, I’ll present computations using p-adic Hodge theory which answer some outstanding questions about CY3s over finite fields. I will not assume familiarity with Calabi-Yau manifolds or p-adic Hodge theory.
