Values of zeta functions of arithmetic surfaces at $s = 1$

S. Lichtenbaum, N. Ramachandran

We show that the recent conjecture of the first-named author for the special value at $s = 1$ of the zeta function of an arithmetic surface is equivalent to the Birch-Swinnerton-Dyer…

Fiber integration of gerbes and Deligne line bundles

Ettore Aldrovandi, Niranjan Ramachandran

Let $π : X \to S$ be a family of smooth projective curves, and let $L$ and $M$ be a pair of line bundles on $X$ . We show that Deligne's line bundle $⟨ L, M ⟩$ can be obta…
