Polyakov action - course on String Theory

Описание: The Polyakov Action

The Polyakov action lies at the heart of string theory, revealing the profound connection between the geometry of spacetime and the behavior of tiny vibrating strings.
In my course, "Mathematical Intuition behind String Theory," I try to unravel the Nambu-Goto action, equations of motion, symmetries, and more. Then we cover the quantization of another action, which is the Polyakov action. We also witness the natural role that the graviton plays in String theory, and we move on to the derivation of Einstein’s field equations from the theory itself!

Expand your knowledge, sharpen your intuition, and discover the elegance that lies within the mathematical foundations of one of the most intriguing theories in modern physics.
