A doctoral thesis begins with a statement of reasons that justifies the need for research based on the current state of affairs. From here, the hypothesis and the main objective to be achieved are proposed, complemented by several more specific ones that will help to reach the proposed goal. To achieve these objectives, a method is designed with which results are achieved. Once obtained, the transfer associated with said findings and a discussion about them are provided. In the discussion, the limitations that the work has had are addressed and exposed, along with the new avenues of investigation that it can open. In summary, a thesis is a rational defence of the proposed hypothesis, a demonstration based on data that is verifiable, citable, traceable, and refutable, in accordance with the channels that the discipline in which the thesis is developed accepts as standard.
