This site presents works of **Alexander Ketsaris** devoted base concepts of theoretical physics.
In particular, a new methodology allowing us to conciliate classical and quantum points of view
on descriptions of physical phenomena is developed in the works. Two key regulations are in a basis of the theory:

- The spacetime and the space of action are generalized to the tensor algebra.
- The translation and transformation groups are fundamental physics groups that determine dynamics of physical systems.

We call your attention to **lecture series**.
In the lectures you can familiarize yourself with the basic logical prerequisites of the theory and its consequences
in a statement focused on the student audience.
