Producing in Urgent Situations:The Management of Unpredictability in the World of Journalism [PDF]
Journalistic work is confronted structurally with urgent situations. Unlike other sectors using just-in-time methods, here urgency is not only the result of random failures in the production cycle, it also relates to the nature of the commodity itself ...

Belyi Function whose Grothendieck Dessin is a Flower Tree with Two Ramification Indices [PDF]
, 2005 In this paper we present an explicit construction of Belyi functions whose dessins are flower trees (i.e., graphs of diameter 4) with two ramification indices.

On Weierstra{\ss} semigroups at one and two points and their corresponding Poincar\'e series
, 2011 The aim of this paper is to introduce and investigate the Poincar\'e series associated with the Weierstra{\ss} semigroup of one and two rational points at a (not necessarily irreducible) non-singular projective algebraic curve defined over a finite field,

On Jacobi Inversion Formulae for Telescopic Curves [PDF]
, 2016 For a hyperelliptic curve of genus $g$, it is well known that the symmetric products of $g$ points on the curve are expressed in terms of their Abel-Jacobi image by the hyperelliptic sigma function (Jacobi inversion formulae). Matsutani and Previato gave

Chip-firing games on Eulerian digraphs and NP-hardness of computing the rank of a divisor on a graph
, 2015 Baker and Norine introduced a graph-theoretic analogue of the Riemann-Roch theory. A central notion in this theory is the rank of a divisor. In this paper we prove that computing the rank of a divisor on a graph is NP-hard.

An effective Arakelov-theoretic version of the hyperbolic isogeny theorem
, 2015 For an integer $e$ and hyperbolic curve $X$ over $\overline{\mathbb Q}$, Mochizuki showed that there are only finitely many isomorphism classes of hyperbolic curves $Y$ of Euler characteristic $e$ with the same universal cover as $X$.
