Extremally Ricci pinched $G_2$-structures on Lie groups

چکیده
Only two examples of extremally Ricci pinched G2-structures can be found in the literature and they are both homogeneous. We study this paper existence structure such very special closed on Lie groups. Strong structural conditions algebra proved to hold. As an application, we obtain three new that all necessarily steady Laplacian solitons. The deformation rigidity structures also studied.

Einstein structures on four-dimensional nutral Lie groups
When Einstein was thinking about the theory of general relativity based on the elimination of especial relativity constraints (especially the geometric relationship of space and time), he understood the first limitation of especial relativity is ignoring changes over time. Because in especial relativity, only the curvature of the space was considered. Therefore, tensor calculations should be to...
متن کاملRicci Yang-mills Solitons on Nilpotent Lie Groups
The purpose of this paper is to introduce the Ricci Yang-Mills soliton equations on nilpotent Lie groups. In the 2-step nilpotent setting, we show that these equations are strictly weaker than the Ricci soliton equations. Using techniques from Geometric Invariant Theory, we develop a procedure to build many different kinds of Ricci Yang-Mills solitons. We finish this note by producing examples ...
متن کاملLorentz Ricci solitons on 3-dimensional Lie groups
The three-dimensional Heisenberg group H3 has three left-invariant Lorentz metrics g1 , g2 and g3 as in [R92] . They are not isometric each other. In this paper, we characterize the left-invariant Lorentzian metric g1 as a Lorentz Ricci soliton. This Ricci soliton g1 is a shrinking non-gradient Ricci soliton. Likewise we prove that the isometry group of flat Euclid plane E(2) has Lorentz Ricci ...
متن کاملMultiplicative Dirac structures on Lie groups
We study multiplicative Dirac structures on Lie groups. We show that the characteristic foliation of a multiplicative Dirac structure is given by the cosets of a normal Lie subgroup and, whenever this subgroup is closed, the leaf space inherits the structure of a Poisson-Lie group. We also describe multiplicative Dirac structures on Lie groups infinitesimally. Résumé Nous étudions les structure...
متن کاملSub-Riemannian structures on 3D Lie groups
We give a complete classification of left-invariant sub-Riemannian structures on three dimensional Lie groups in terms of the basic differential invariants. As a corollary we explicitly find a sub-Riemannian isometry between the nonisomorphic Lie groups SL(2) and A(R)× S, where A(R) denotes the group of orientation preserving affine maps on the real line.
