Gauge theories are theories with ‘local symmetries’, that is, theories that remain invariant under transformation of a variable quantity that is ‘local’ (‘infinitesimal’ would be more exact) in the sense that its value expressly depends on the space and time coordinates. The quantum field theories that comprise the so-called Standard Model of elementary particles – the current best understanding of the non-¬gravitational fundamental interaction – are quantized gauge theories, also known as Yang-Mills ¬theories.

FN1515) For example, in the Heisenberg representation, wave functions are independent of time but operators are time-dependent; whereas in the Schrödinger representation the time-dependences are reversed. Heisenberg’s version, with its emphasis on manipulation of operators appears very different from the Schrödinger equation, which is a differential equation in configuration space. In any case, the two representations are equivalent for all empirical predictions.

Each branch represents a different outcome of the measurement and the corresponding eigenstate for the object-system state [our S – TR].
