Lifting diffeomorphisms to vector bundles
Jaime Muñoz Masqué, Eugenia Rosado María, Ignacio Sánchez Rodríguez
Criteria for a diffeomorphism of a smooth manifold to be lifted to a linear automorphism of a given real vector bundle , are stated. Examples are includ…
A group law on the projective plane with applications in Public Key Cryptography
R. Durán Díaz, V. Gayoso Martínez, L. Hernández Encinas +1
We present a new group law defined on a subset of the projective plane over an arbitrary field , which lends itself to applications in Public Key Crypto…
Second-order Lagrangians admitting a first-order Hamiltonian formalism
E. Rosado María, J. Muñoz Masqué
Second-order Lagrangian densities admitting a first-order Hamiltonian formalism are studied; namely, i) for each second-order Lagrangian density on an arbitrary fibred manifold $p\…
First-order equivalent to Einstein-Hilbert Lagrangian
Marco Castrillon Lopez, Jaime Munoz Masque, Eugenia Rosado Maria
A first-order Lagrangian variationally equivalent to the second-order Einstein-Hilbert Lagrangian is introduced. Such a Lagrangian depends on a symmetric linear connect…
The Equivalence Problem of Curves in a Riemannian Manifold
M. Castrillon Lopez, V. Fernandez Mateos, J. Munoz Masque
The equivalence problem of curves with values in a Riemannian manifold, is solved. The domain of validity of Frenet's theorem is shown to be the spaces of constant curvature. For a…
Diffeomorphism-invariant Covariant Hamiltonians of a pseudo-Riemannian Metric and a Linear Connection
J. Muñoz Masqué, M. Eugenia Rosado María
\noindent Let (resp.\ ) be the fibre bundle of pseudo-Riemannian metrics of a given signature (resp.\ the bundle of linear connections) on an orientable connected…
