Variational Approach to Gravity Field Theories

This book offers a detailed and stimulating account of the Lagrangian, or variational, approach to general relativity and beyond. After an introduction to field theories and the variational approach, individual sections focus on the variational approach in relation to special relativity, general relativity, and alternative theories of gravity.

Aceasta carte ofera o descriere detaliata si stimulanta a abordarii lagrangiene sau variationale a relativitatii generale si nu numai. Dupa o introducere in teoriile de camp si abordarea variationala, sectiunile individuale se concentreaza pe abordarea variationala in raport cu relativitatea speciala, relativitatea generala si teoriile alternative ale gravitatiei.
