Algebraic structures, such as groups, rings and fields, provide a rigorous language for expressing symmetry and invariance in numerous mathematical contexts. Their integration with the theory of ...

Superintegrable systems represent a fascinating class of models in both classical and quantum mechanics, characterised by the existence of more independent constants of motion than would be expected ...

Defining a composition operation on sets of formulas one obtains a manysorted algebra which satisfies the superassociative law and one more identity. This algebra is called the clone of formulas of ...
