As is shown in many calculus texts, by using the mean value theorem instead of the fundamental theorem of calculus, one can obtain a slightly Web6 Jun 2024 · A vector field $ X $ on a manifold $ M ^ {2n} $ with a Hamiltonian structure is called a Hamiltonian vector field (or a Hamiltonian system) if the $ 1 $- form $ \omega _ {X} $ is closed. If, in addition, it is exact, that is, $ \omega _ {X} = - dH $, then $ H $ is called a Hamiltonian on $ M ^ {2n} $ and is a generalization of the corresponding classical concept.

Web12 Apr 2024 · The generalized Weinberg–Salam model, which is presented in a recent study of Kimm, Yoon, and Cho [Eur. Phys. J. C 75, 67 (2015)], is arising in electroweak theory.In this paper, we prove the existence and asymptotic behaviors at infinity of static and radially symmetric dyon solutions to the boundary-value problem of this model. WebA Semispray structure on a smooth manifold M is by definition a smooth vector field H on TM \0 such that JH=V. An equivalent definition is that j(H)=H, where j:TTM→TTM is the canonical flip. A semispray H is a spray, if in addition, [V,H]=H. Spray and semispray structures are invariant versions of second order ordinary differential equations ...
