Diferenciální invarianty metrického tenzoru

Abstract

This thesis discusses, on an introductory level, the theory of differential invariants and their construction using the “orbit reduction method“, which consists of the decomposition of differential invariants by means of suitable factorization of the domain. In our case, it is a space of 2.-nd order metric tensors, on which acts a differential group (generalizing general linear group). From the point of view of this theory, we discuss the famous Hilbert Lagrangian in general relativity theory, and we show that it results in scalar invariance of the metric tensor
