Abstract
Two important aspects in physics are the invariance (or symmetry) of the equations describing the behavior of a system under a given transformation (for example, a translation of the system frame) and the conservation of some physical quantities (e.g., the momentum). The invariance properties are abstract features of the mathematical formalism. These invariance properties are intimately connected to conservation laws. Transformations can be continuous or discrete. A rotation is an example of continuous transformations; the mirror reflection in space is an example of discrete transformations. The conservation laws related to these transformations are respectively additive and multiplicative, and some problems on the effect on some reactions involving particles are presented.
