The aim of this work is to highlight the connections obtained between the Fibonacci Series, the Golden Ratio and the Golden Section Ovaloids, with String Theory. The first two chapters deal with (1) the Golden Angle and (2) the Fibonacci Series and the ovaloid (egg) with the golden section. The following chapters describe the mathematical theory of functional transformations and that of ovaloids, connected to it, from the point of view of the Theory of Complex Variable Functions, which will be followed by some interesting mathematical aspects of String Theory connected both to the ovaloids and to the relationship aureus and the golden section. Finally, a unitary theory of matter and the Universe by the scholar and theorist M. Giannone will be exhibited, in whose equations the golden section, the golden ratio and the constant of the musical system in the golden section are inherent. This work involves the very current research " frontier ”which are being implemented in this period as part of what is called the Langlands Program.
