4 = 2 × 2, or the Power of Even Integers in Fourier Analysis
[SNAP-2023-006-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-12-30)We describe how simple observations related to vectors of length 1 recently led to the proof of an important mathematical fact: the sharp Stein–Tomas inequality from Fourier restriction theory, a pillar of modern harmonic ... -
Algebras and Quantum Games
[SNAP-2023-004-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-11-28)Everyone loves a good game, but when the players can access the counterintuitive world of quantum mechanics, watch out! -
Cutoff Phenomenon: Surprising Behaviour in Card Shuffling and other Markov Chains
[SNAP-2023-005-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-12-21)This snapshot compares two techniques of shuffling a deck of cards, asking how long it will take to shuffle the cards until a “well-mixed deck” is obtained. Surprisingly, the number of shuffles can be very different for ... -
Cutoff-Phänomen: überraschendes Verhalten beim Kartenmischen und bei weiteren Markovketten
[SNAP-2023-005-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2024-10-22)Dieser Schnappschuss vergleicht zwei Arten des Kartenmischens und untersucht, wie lange es dauert einen "gut gemischten" Kartenstapel zu erhalten. Überraschenderweise kann das Mischverhalten auch für sehr ähnlich ausschauende ... -
Felder und Räume: Symmetrie und Lokalität in Mathematik und theoretischen Wissenschaften
[SNAP-2023-003-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2023-09-19)Wir werden einige grundlegende Ideen der Eichtheorie und der dazugehörigen Differentialtopologie erkunden. Damit kann sich die Leserin ein Bild des Modulraums flacher Zusammenhänge machen und ihn mit den physikalisch ... -
The Geometry of Fair Division
[SNAP-2023-007-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-12-30)How can we fairly divide a necklace with various types of beads? We use this problem as a motivating example to explain how geometry naturally appears in solutions of non-geometric problems. The strategy we develop to solve ... -
Geproci Sets: a New Perspective in Algebraic Geometry
[SNAP-2023-008-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-12-30)Geproci sets arise from applying the perspective of inverse scattering problems to algebraic geometry. Analogous to the reconstruction of an object from multiple X-ray images, we aim at a classification of sets with certain ... -
Patterns and Waves in Theory, Experiment, and Application
[SNAP-2023-001-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-07-04)In this snapshot of modern mathematics we describe some of the most prevalent waves and patterns that can arise in mathematical models and which are used to describe a number of biological, chemical, physical, and social ... -
The Periodic Tables of Algebraic Geometry
[SNAP-2023-002-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2023-09-04)To understand our world, we classify things. A famous example is the periodic table of elements, which describes the properties of all known chemical elements and gives us a classification of the building blocks we can use ...
