heal.abstract |
Στην εργασία αυτή περιγράφονται τα βασικά χαρακτηριστικά των βαρυτικών κυμάτων, που προκύπτουν ως λύση των εξισώσεων Einstein σε γραμμική προσέγγιση.Ακόμα, εξετάζονται οι βασικές μέθοδοι ανίχνευσης βαρυτικών κυμάτων, με έμφαση στη συμβολομετρία. |

This thesis explores gravitational waves as solutions of the Einstein equations according to a linear approach. Chapter rst begins with a brief introduction of the Lagrangian and the Hamilto-nian formalism in classical mechanics, since a similar formalism will lead us to the Einstein-Hilbert action, wherefrom we shall derive the Einstein equations. In another chapter we analyse special relativity, it being a prerequisite in order to move on to the general theory of relativity. Further-more, we present in detail the formalisms of differentiable manifolds and of differential geometry which are the mathematical tools to describe spacetime as a pseudo-Riemannian manifold. We
then derive the Einstein equations. Following that, we derive the solutions of the linearized Ein-stein equations that take the form of a wave and analyse their main characteristics. Finally, the last chapter presents the basic principles of gravitational wave detection, while special mention is made to their recent discovery by LIGO observatory. |
