Abstract

Let $\E/\Q$ be a fixed elliptic curve over $\Q$ which does not have complex multiplication. Assuming the Generalized Riemann Hypothesis, A. C. Cojocaru and W. Duke have obtained an asymptotic formula for the number of primes $p\le x$ such that the reduction of $\E$ modulo p has a trivial Tate-Shafarevich group. Recent results of A. C. Cojocaru and C. David lead to a better error term. We introduce a new argument in the scheme of the proof which gives further improvement.

A Database of Continued Fractions of Polynomial Type

We describe a database of 1925 continued fractions with polynomial coefficients, of which more than 1600 are new, both for interesting constants and for transcendental functions, and provide the database inside the \TeX\ source of the paper. Look in particular at the section ``Table of Contents''.

On properness of moduli stacks of $D^{\times}$-shtukas over ramified legs

Given a maximal order $\mathcal{D}$ of a central division algebra $D$ over a global function field $F$, we prove an explicit necessary and sufficient condition for moduli stacks of $\mathcal{D}^\times$-shtukas to be proper over a finite field (modulo a suitable central action) in terms of the local invariants of $D$ and bounds. Our result extends E. Lau's criterion (Duke Math. J. 140 (2007)) for properness of the leg morphism (or characteristic morphism) away from the ramification locus of $D$ to allow legs at ramified places. We also establish non-emptiness of Newton and Kottwitz-Rapoport strata for moduli stacks of $\mathcal{B}^\times$-shtukas, where $\mathcal{B}$ is a maximal order of a central simple algebra over $F$.

Cuspidal distinction via intertwining periods

Local intertwining periods have so far been used to reduce distinction of a general irreducible representation to distinction of cuspidal ones, for which other tools -- type theory, local and global trace formulae -- take over. The main contribution of this paper is to prove that they can be used to decide distinction of cuspidal representations themselves. We develop this approach with three well-studied examples for which the ambient group is an inner form of $\mathrm{GL}_n$ over a $p$-adic field, namely linear models, their non-split twisted version, and the quaternionic symplectic model. As consequences, we obtain proofs valid in arbitrary residual characteristic of the cuspidal case of the epsilon dichotomy conjecture of Prasad and Takloo-Bighash and of Prasad's conjecture on quaternionic symplectic models. The proof in the quaternionic symplectic model case, although going through intertwining periods, uses the simplest ones, namely closed intertwining periods, and is disappointingly short and elementary.
