Structured and Punctured Nullstellensätze
A Nullstellensatz is a theorem providing information on polynomials that vanish on a certain set: David Hilbert's Nullstellensatz (1893) is a cornerstone of algebraic geometry, and Noga Alon's Combinatorial Nullstellensatz (1999) is a powerful tool in the "Polynomial Method", a technique used in combinatorics. Alon's Theorem excludes that a polynomial vanishing on a grid contains a monomial with certain properties. This theorem has been generalized in several directions, two of which we will co…

Nihilistische Gewalt, um Berühmtheit in einem Milieu zu erlangen, das Massenmörder verehrt:
Das ist der rote Faden bei Amokläufen der letzten 25 Jahre. Kein politisches Motiv, kein (primär) persönliches – sondern eine Onlinebewegung, die Mordvideos mag.
