On three-manifolds dominated by circle bundles [PDF]

, 2012
We determine which three-manifolds are dominated by products. The result is that a closed, oriented, connected three-manifold is dominated by a product if and only if it is finitely covered either by a product or by a connected sum of copies of the ...

Tropicalization of the moduli space of stable maps [PDF]

, 2015
Let $X$ be an algebraic variety and let $S$ be a tropical variety associated to $X$. We study the tropicalization map from the moduli space of stable maps into $X$ to the moduli space of tropical curves in $S$.

On the non-abelian Brumer-Stark conjecture and the equivariant Iwasawa main conjecture [PDF]

, 2018
We show that for an odd prime p, the p-primary parts of refinements of the (imprimitive) non-abelian Brumer and Brumer-Stark conjectures are implied by the equivariant Iwasawa main conjecture (EIMC) for totally real fields.

Long‐Term Follow‐Up of Patients with Mass Social Media‐Induced Illness Presenting with Functional Tic‐like Behaviors

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Only little is known about the prognosis of functional tic‐like behaviors (FTLB), especially in the subgroup of patients with mass social media‐induced illness (MSMI‐FTLB). Objectives To provide data of long‐term follow‐up (FU) of a carefully characterized group of patients with MSMI‐FTLB to identify influencing factors such as ...
