Deriving the cosmological constant from the Euler–Lagrange equation of second-order differentiable gravitational field Lagrangian
The principles underlying the variational approach prove to be invaluable tools in articulating physical phenomena, particularly when dealing with conserved quantities. The derivation of gravitational field equations from the Euler–Lagrange equation, a result of the first-order derivative of Lagrang...
