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 ...

Entanglement is a resource that is utilized on quantum devices to cary information on quantum bits (qubits), and is what gives a quantum computer its theoretical advantage over its classical ...

For any fiat 2-category C, we show how its simple transitive 2-representations can be constructed using co-algebra 1-morphisms in the injective abelianization of C. Dually, we show that these can also ...
