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 ...

A previous paper, 'Invariant theory, tensors and group characters', dealt with invariant theory under the full linear group. In this paper the methods are extended to restricted groups of ...
