RT info:eu-repo/semantics/bachelorThesis T1 An introduction to bosonic string theory A1 Bravo Pérez, Himar K1 Symmetry K1 Constraints K1 Action AB This final degree project is thought to be a theoretical enlargement of the degree knowledge in order to broaden the basic concepts of mathematics and theoretical physics applied to the formulation ofString theory.In this essay, we will make an introduction to the theory of quantum bosonic strings. The ultimate objective of this final project will be to formulate the hypothetical gravity force carrier particle, and how to recover the Einstein´s equations from String theory.This piece of work will commence by making a classical approach to the relativistic string for the purpose of formulating important results that we will use to quantize it.We will quantize the theory in three different ways. Firstly, the Canonical Quantization will be applied, secondly, the Lightcone Quantization will be used and, lastly, we will utilize the one needed in order to formulate the general relativity which is The Path Integral approach.
