    The unitary representations of groups and algebras are of a great interest in physics. We can mention the ubiquitous example of angular momentum or the SU(2) algebra. In this instance, as it is well known, the representations are labeled by . Figure Mechanical representation of the classical wave equation The acceleration of the masses (the second order derivative in time) is given by the force which is exerted by the springs. The force is given by the second order derivative in x, in combination with the strength of the springs given by parameter v2: Classical Wave equation.

    For example, in relativistic quantum mechanics, we classify particles as unitary irreducible representations (or ‘irreps’) of a group like this: G × P G \times P Here G G is a compact Lie group depending on the theory of physics we happen to be studying, called the ‘internal symmetry group’. Finally, covariant wave equations are given for each unitary irreducible representation of the Poincaré group with non-negative mass-squared. Tachyonic representations are also examined. All these steps are covered in many details and with examples.

    can describe a unitary representation of T by a function d:L∗ → N. This function d deserves a snappy name, so let’s call it the weighting of the representation. We call d(ℓ) the multiplicity of the weight ℓ. More generally, if ρ:K → U(H) is a unitary representation of a compact simply-connected simple Lie group, we can restrict ρ to. The Majorana-Fourier and Majorana-Hankel transforms of Majorana spinor fields are defined and related to the linear and angular momenta of a spin one-half representation of the Poincare group. We show that the Majorana spinor field with finite mass is an unitary irreducible projective representation of the Poincare group on a real Hilbert space.
