Unexpected Primes of Good Reduction in Quotients of Modular and Shimura Curves

Mathematische Nachrichten, EarlyView.
ABSTRACT We find all zero‐dimensional spaces of newforms of weight 2 and squarefree level N$N$ with a fixed Atkin–Lehner sign pattern. As an application, we classify unexpected primes of good reduction of Atkin–Lehner quotients of modular and Shimura curves of squarefree levels.

Combinatorics, Words and Symbolic Dynamics

, 2016
Internationally recognised researchers look at developing trends in combinatorics with applications in the study of words and in symbolic dynamics. They explain the important concepts, providing a clear exposition of some recent results, and emphasise ...

Forbidden intersection problems for families of linear maps

Discrete Analysis, 2023
Forbidden intersection problems for families of linear maps, Discrete Analysis 2023:19, 32 pp. A central problem in extremal combinatorics is to determine the maximal size of a set system given constraints on the sizes of the sets in the system and on ...

On the Contribution of WORDS to the Field of Combinatorics on Words [PDF]

, 2015
We propose some notes about the history and the features of the conference WORDS, our goal being to testify how the conference may be embedded in the development of the field of Combinatorics on Words.

Against All Odds?—A Surprisingly Not So Easy Dice Game

Teaching Statistics, EarlyView.
ABSTRACT A game with 11 players, 2 dice, and simple rules. However, it turns out that the best strategy is not only absent from the literature, but that misconceptions about winning strategies also prevail among surveyed students. This makes it all the more surprising that it is not so easy to get to the bottom of the game mathematically.

Shuffle Product Formulas and Combinatorial Identities

Mathematics
We study shuffle product structures on words in three letters, extending the classical framework of multiple zeta values. Using an evaluation map that relates admissible words to iterated integrals, we translate shuffle identities into combinatorial ...

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

On the Limits of Intransitive Coordination

Ratio, EarlyView.
ABSTRACT A growing number of authors suggest that concept coordination—the kind of relation we pick out when we say that the concepts of one or more individuals represent something as the same—is not a transitive relation. Here we consider global features of representational systems to break new ground in the assessment of the intransitivity view. From
