Involutivity of the Hamilton-Cartan equations of a second-order Lagrangian admitting a first-order Hamiltonian formalism

The arbitrary and differential nature of the linguistic sign and the non-correspondence of language and reality is the linguistic basis for the structuralist idea that all meaning

Our results here also indicate that the orders of integration are higher than 1 but smaller than 2 and thus, the standard approach of taking first differences does not lead to

In the “big picture” perspective of the recent years that we have described in Brazil, Spain, Portugal and Puerto Rico there are some similarities and important differences,

First (a,d), second (b,e) and third (c,f) columns correspond to the first-, second- and third-order EMHPM, respectively. 69 Figure 4.6 Representation of the first-order

First and foremost, we developed a theoretical framework identifying seven first-order factors that can be explained by a single second-order factor in the context of online

The main goal of this work is to extend the Hamilton-Jacobi theory to different geometric frameworks (reduction, Poisson, almost-Poisson, presymplectic...) and obtain new ways,

The second case is a non-trivial generalization of the formalism consisting in substituting the structure group U(1) of phase invariance by a bigger group T (to account for

Remarkable among the former are the economic results or contribution of the second-order co-operative to the objectives of the first-order co-operatives, the trust inspired in
