*A*pertaining to a particle constrained on a sphere, which is generated by the coordinates

**n**and by the angular momentum

**J**.

*A*is the algebra

*E*

_{3}of the Euclidean group in space. We find its irreducible representations by a novel approach, by showing that they are the irreducible representations (

*l*

_{0}, 0) of

*so*(3, 1) , with l

_{0}or -l

_{0}being equal to the Casimir operator

**J**...

*ad hoc*solutions for each problem, the field has evolved gradually to use or reuse systems developed across the years for the same environment or coming from other fields with the same requirements. Several frameworks have emerged to solve common problems. In High Energy Physics...

*p*-type GaSb were studied theoretically as a function of temperature from 10K up to 300K. The mobility calculations were based on the relaxation time approximation taking into account elastic scattering mechanisms including lattice and ionized-impurity types. The results showed that the ionized-impurity scattering is the dominant mechanism at low-temperature...

*C*is not a symmetry, the limit of this operation does exist for the particular case when the electromagnetic field is considered a classical external object coupled to the Dirac field. This result extends the one obtained when fermions are described by the Schrödinger-Pauli equation. We give the expressions for both the

*C*matrix and...

*SU*(2) and

*SU*(3) gauge theories by including quarks and gluons and also by reactivating the suppressed dynamical gauge degrees of freedom, the study of dyonic condensation, quark confinement and superconductivity (dual superconductivity as well as color superconductivity) has been undertaken in extended RCD. It has been shown that the global structure...
