Remarks on Hamiltonian Structures in G_2-Geometry
Hyunjoo Cho, Sema Salur, Albert J. Todd
In this article, we treat G_2-geometry as a special case of multisymplectic geometry and make a number of remarks regarding Hamiltonian multivector fields and Hamiltonian different…
Diffeomorphisms of 7-Manifolds with Coclosed G_2-Structure
Sema Salur, Albert J. Todd
We introduce coG_2-vector fields, coRochesterian 2-forms and coRochesterian vector fields on manifolds with a coclosed G_2-structure as a continuous of work from [15], and we show…
Contact Structures on G_2-Manifolds and Spin 7-Manifolds
M. Firat Arikan, Hyunjoo Cho, Sema Salur
We show that there exist infinitely many pairwise distinct non-closed G_2-manifolds (some of which have holonomy full G_2) such that they admit co-oriented contact structures and h…
Existence of Compatible Contact Structures on -manifolds
M. Firat Arikan, Hyunjoo Cho, Sema Salur
In this paper, we show the existence of (co-oriented) contact structures on certain classes of -manifolds, and that these two structures are compatible in certain ways. Moreov…
A Note on Closed G_2-Structures and 3-Manifolds
Hyunjoo Cho, Sema Salur, Albert J. Todd
This article shows that given any orientable 3-manifold X, the 7-manifold T^*X x R admits a closed G_2-structure varphi=Re(Omega)+omega\wedge dt where Omega is a certain complex-va…
Diffeomorphisms of 7-Manifolds with Closed G_2-Structure
Hyunjoo Cho, Sema Salur, Albert J. Todd
We introduce G_2-vector fields, Rochesterian 1-forms and Rochesterian vector fields on manifolds with a closed G_2-structure as analogues of symplectic vector fields, Hamiltonian f…
