On the Relation between Squeezing and Evolution

The squeezing concept has been lately an object of scrutiny in the physical literature. Here we put in the mathematical form the idea that it may be essential for understanding the evaluation and interrelationship of physical systems. The squeezing is defined as a parameter process and then it is shown in what condition the squeezing and the evolution can be described in the same time scale. The meaning of this time scale is given with respect to a kinematics
