Topological materials – materials whose surface properties are very different to those in their bulk – have come to the fore in recent years and are currently revolutionizing modern condensed matter ...

Invariants and elasticity tensors play a pivotal role in the mathematical and physical description of material behaviour. By characterising properties that remain unchanged under coordinate ...

When Lisa Piccirillo solved a decades-old mystery about the “Conway knot,” she had to overcome the knot’s uncanny ability to hoodwink some of the most powerful tools mathematicians have devised. Known ...

With a newly discovered mathematical tool, researchers are hoping to gain unprecedented insight into the structure of complex ...

Invariants should be well-formed formulas, that is, they should be logical statements (with a truth-value--true, of course), in the predicate calculus or rigorous English. A good invariant is a ...

Informally, a dynamic system is any physical system that evolves with time (e.g., a pendulum, a planet orbiting the sun, the weather, etc). From a more mathematically precise perspective, one can ...

Se dit d'un nombre, d'une fonction ou de n'importe quel élément d'un ensemble qui est sa propre image dans une transformation ponctuelle. Exemple : dans la transformation qui à x réel associe 3x, le ...

VANCOUVER - BTQ Technologies Corp. (NASDAQ:BTQ) a annoncé mercredi que le directeur quantique Dr. Gavin K. Brennen a co-écrit une recherche introduisant une théorie générale de la correction d’erreurs ...
