An Introduction to time generation on Algebraic Quantum Field Theory

In the early 2000s, the study of time operators advanced as one of the methods to understand the problem of time as mathematical science. However, the starting point for the time operator is to understand time as a problem of observation (the survival probabilityof particles), and today, even after the issue of representation on time operator has concluded, the question of philosophical interpretation still exists. Furthermore, when it comes to the question of how time generation (emergence), the method of time operators has its limitations. Regarding the generation of time, symmetry breaking in particle physics seems to be closely related.

When does "Time" become "Observable" ?

We investigate some spectral properties of time operators which are obtained through Canonical Commutation Relation (CCR) and Positive Operator Valued Measure (POVM) of quantum physics. In addition, we re-interpret the spectral properties of time operators from the standpoint of the Copenhagen Interpretation, especially, of W.Heisenberg.

Time representation on the Beginning of space-time -- From a philosophical and mathematical view

I would like to consider the Beginning of space-time in this paper. First of all, we do consideration historical thought. A lot of philosophers have considered the relation between this real phenomenal world and the basic world in which the phenomenal world is grounded. We will glimpse thought historical details about such respect. Afterwards, we interpret the representation of space-time on Quantum theory and Relativistic theory. In this case, we will take recent results of time operator theory into consideration.
