Some exact sequences associated with adjunctions in bicategories. Applications

We prove that the classical result asserting that the relative Picard group of a faithfully flat extension of commutative rings is isomorphic to the first Amitsur cohomology group still is valid in the realm of symmetric monoidal categories. To this end, we build some group exact sequences from an a...
