The Lagrange–Charpit theory is a geometric method of determining a complete integral by means of a constant of the motion of a vector field defined on a phase space associated to a nonlinear PDE of first order. In this article, we establish this th

In this article we develop a generalization of the Hamilton-Jacobi theory, by considering in the cotangent bundle an involutive system of dynamical equations.

We shall call quantum states of a principal bundle π : P → M with structure group a semi-simple Lie group G, the elements of certain space \({\mathcal{H}}\) of sections of the adjoint bundle \({\pi _{\mathcal{G}} : ad(J^{1}P) \rightarrow \mathcal{

In this article we classify higher-order gauge invariant Lagrangian densities on the bundle of connections of a principal G -bundle π : P → M , in the case where the structure group is abelian. Also we show the strong obstruction for an analogous

We solve, for irreducible representations, a conjecture proposed by D. Eck, analogous to the classical Hilbert theorem on polynomial invariants, relative to the k -jet action of a compact Lie group.

A case is presented of an 84 year-old woman who was admitted to the Emergency Department due to an episode of non-calculous acute pancreatitis. In the aetiological study, the presence of a splenic lymphoma was documented, which had a compressive effe
