Die Bundes-CDU scheint sich immer mehr zur AfD zu treiben. Wer nicht voll auf der teils rassistischen Linie der Parteiführung ist, wird irrational angegriffen. Anstand und Sachverstand scheinen keine Rolle zu spielen, wenn die Konsequenzen daraus den Träumen des Bundeskanzlers widersprechen.
Der Machtkampf in der CDU ist übel. Demokratische Positionen, Positionen der Menschenrechte und des Anstands scheinen immer weniger Platz in der CDU zu bekommen.

Well-posedness for the periodic Hyperbolic nonlinear Schrödinger equations
We establish local well-posedness for the hyperbolic nonlinear Schrodinger equation (HNLS) in the critical spaces. Following the approach of Killip and Visan, we derive scale-invariant Strichartz estimates for HNLS on both rational and irrational tori, thereby removing the epsilon-loss of derivative present in the hyperbolic Strichartz estimates of Bourgain and Demeter.

On the $b$-ary expansion of a real number whose irrationality exponent is close to 2

On the $b$-ary expansion of a real number whose irrationality exponent is close to 2
Let $b \ge 2$ be an integer and $ξ$ an irrational real number. We establishes that, if the irrationality exponent of $ξ$ is less than $2.324 \ldots$, then the $b$-ary expansion of $ξ$ cannot be `too simple', in a suitable sense. This improves the results of our previous paper [Ann. Sc. Norm. Super. Pisa Cl. Sci., 2017].

Ever so fitting for our trying times, and a growing conflict for quite a few people (incl. myself), I imagine...
"Absurdism is the philosophical theory that the universe is irrational and meaningless. It states that trying to find meaning leads people into conflict with a seemingly meaningless world. This conflict can be between rational humanity and an irrational universe, between intention and outcome, or between subjective assessment and objective worth..."

Climate deniers' online strategy: Using scientific aesthetics to appear credible
Climate deniers use scientific aesthetics to reinforce and legitimize their message. At the same time, their main opponents, the climate activists, are portrayed as emotional and irrational. This has been demonstrated by researchers from the Universities of Gothenburg and Amsterdam, who have studied how climate deniers communicate online. The results are published in Environmental Politics.

On the Uniqueness of Ein(1) among Linear Combinations of the Euler-Mascheroni and Euler-Gompertz Constants

On the Uniqueness of Ein(1) among Linear Combinations of the Euler-Mascheroni and Euler-Gompertz Constants
From a well-known equation of Hardy, one can derive a simple linear combination of the Euler-Mascheroni constant ($γ=0.577215\ldots$) and Euler-Gompertz constant ($δ=0.596347\ldots$): $γ+δ/e=\textrm{Ein}\left(1\right)$. Although neither $γ$ nor $δ$ is currently known to be irrational, this linear combination has been shown to be transcendental (by virtue of the fact that it appears as an algebraic point value of a particular E-function). Moreover, both pairs ($γ$,$δ$) and ($γ$,$δ/e$) …

Balanced Fibonacci word rectangles, and beyond
Following a recent paper of Anselmo et al., we consider $m \times n$ rectangular matrices formed from the Fibonacci word, and we show that their balance properties can be solved with a finite automaton. We also generalize the result to every Sturmian characteristic word corresponding to a quadratic irrational.

A modular version of the Brunn-Minkowski inequality and its applications
Let $α>1$ be an irrational number and $k\ge 2$ a positive integer. Let $f(x)$ be a polynomial with positive integer coefficients. Solving a 2001 problem of Sárközy on special sequences, Hegyvári proved in 2003 that there exists an infinite sequence $A$ with density $\frac{1}{k}-\frac{1}{kα}$ such that $$ \big\{f(a_1)+\ldots+f(a_k): a_i\in A, 1\le i\le k\big\}\cap \big\{\lfloor nα\rfloor: n\in \mathbb{N}\big\}=\emptyset. $$ Hegyvári also proved that the density given by him is optimal for…

Why people embrace conspiracy theories: It's about community, not gullibility
Psychologists have long considered how a tendency towards irrational thinking or particular personality traits might predict people's interest in conspiracies. Yet these individual factors do not explain the group processes through which conspiracy theorists are extending their influence and impact.

Universal codimension two cycle on a very general cubic threefold
In this paper, we prove that a very general cubic threefold does not admit a universal codimension-two cycle and hence is stably irrational.

Convergence exponent of Dirichlet non-improvable numbers in the theory of continued fractions
Let $x \in [0,1)$ be an irrational number with continued fraction expansion $[a_1(x),a_2(x), \cdots,a_n(x),\cdots]$ and $q_n(x)$ be the denominator of its $n$-th convergent. We establish, for any $α,β$ in $[0,+\infty]$, the Hausdorff dimension formula of the intersections of the sets of Dirichlet non-improvable numbers and the level set of convergent exponent, i.e. $$ G(α,β): =\left\{x\in[0,1)\colon τ(x)=α,\,\,\text{and} \,\, \limsup_{n\to\infty}\frac{\log (a_n(x)a_{n+1}(x))}{\log q_n(x…

On roundness of rotation sets
Motivated by the question whether a round disk can be realized as the rotation set of a torus diffeomorphism, we study the roundness of rotation sets of a parametric family of torus diffeomorphisms $F_ρ$, where the parameter $ρ$ ranges over irrational numbers in $(0,1)$. Each $F_ρ$ is a Kwapisz-like diffeomorphism with a 2-dimensional non-polygonal rotation set $$Λ'_ρ= \operatorname{conv}\left(\left\{(\pm\frac{\lceil mρ\rceil}{m+n+1}, \pm\frac{\lceil nρ\rceil}{m+n+1}): m, n \in \mathbb…

Distinct Distances on Pfaffian Curves
We generalize Pach and de Zeeuw's bound for distinct distances between points on two curves, from algebraic curves to Pfaffian curves. Pfaffian curves include those that can be defined by any combination of elementary functions, including exponential and logarithmic functions, rational and irrational powers, trigonometric functions and their inverses, integration, and more. The bound remains $Ω(\min\{m^{3/4}n^{3/4},m^2,n^2\})$, as obtained from the proximity technique of Solymosi and Zahl.
