A Machian Approach to Relativistic Cosmology
Enrico Massa, Davide Astesiano
We present a consistent relativistic formulation of Mach principle within a geometric theory of gravitation. In this approach, neither inertia nor free fall is assumed a priori. In…
Small oscillations of non-dissipative Lagrangian systems
Enrico Massa, Stefano Vignolo
The small oscillations of an arbitrary scleronomous system subject to time-independent non dissipative forces are discussed. The linearized equations of motion are solved by quadra…
Floating rigid bodies: a note on the conservativeness of the hydrostatic effects
Enrico Massa, Stefano Vignolo
Within the framework of Lagrangian mechanics, the conservativeness of the hydrostatic forces acting on a floating rigid body is proved. The representation of the associated hydrost…
Variational techniques in general relativity: A metric-affine approach to Kaluza's theory
Enrico Massa, Stefano Vignolo
A new variational principle for General Relativity, based on an action functional $I\/(Φ,\nabla)\/$ involving both the metric $Φ\/$ and the connection $\nabla\/$ as independent, \e…
A vielbein formulation of unified Einstein-Maxwell theory
Stefano Vignolo, Enrico Massa
In the framework of J-bundles a vielbein formulation of unified Einstein-Maxwell theory is proposed. In the resulting scheme, field equations matching the gravitational and electro…
A new geometrical look at Ostrogradsky procedure
Enrico Massa, Stefano Vignolo, Roberto Cianci +1
Making use of the modern techniques of non-holonomic geometry and constrained variational calculus, a revisitation of Ostrogradsky's Hamiltonian formulation of the evolution equati…
