A research series in structural mathematics

The Classification of Mathematical Representations of Physical Systems

A representation is recorded as a five-part tuple of state space, observables, dynamics, symmetries, and composition rules. The series fixes a morphism vocabulary with explicit preservation laws, classifies restricted classes in full, and states the structural classification conjecture with its five proof obligations. Twelve volumes, one synthesis.
