On the classification of symplectic DQ-algebroids
Paul Bressler, Juan Diego Rojas
DQ-algebroids locally defined on a symplectic manifold form a 2-gerbe. By adapting the method of P. Deligne to the setting of DQ-algebroids we show that this 2-gerbe admits a canon…

Santiago Arango-Piñeros, Juan Diego Rojas
Using a remainder theorem for valuations of a field, we give a new perspective on the norm function of a global field. We define the Euler totient function of a global field and re…
