چکیده
We describe the second order obstruction to deformation for nearly G 2 structures on compact manifolds. Building work of Alexandrov and Semmelmann, this allows proving rigidity under proper structure Aloff–Wallach space N ( 1 , ) .

Deformations in G2 Manifolds
Here we study the deformations of associative submanifolds inside a G2 manifold M 7 with a calibration 3-form φ. A choice of 2-plane field Λ on M (which always exists) splits the tangent bundle of M as a direct sum of a 3-dimensional associate bundle and a complex 4-plane bundle TM = E ⊕ V, and this helps us to relate the deformations to SeibergWitten type equations. Here all the surveyed resul...
متن کاملDeformations of Complex Structures
In this section, we discuss briefly how to compare different almost complex structures on a manifold. Let M be a fixed compact manifold, TM its tangent bundle. Let J ∈ End(TM ) be an almost complex structure on M , with associated decomposition TM ⊗ C ' TM 0,1 ⊕ TM 1,0, and projections π0,1 and π1,0 to the two summands. Now suppose J ′ is a second almost complex structure. The reader should thi...
متن کاملDeformations of Hypercomplex Structures
Twistor theory shows that deformations of a hypercomplex manifold correspond to deformations of a canonically constructed holomorphic map from the twistor space of the hypercomplex manifold onto the complex projective line. Applying Horikawa's theory of deformations of maps, we calculate deformations of compact quotients and twists of the associated bundles of quaternionic manifolds. In particu...
متن کاملThe Second Dirac Eigenvalue of a Nearly Parallel G2-manifold
is the smallest eigenvalues of the square of the Riemannian Dirac operator D, see [6]. The question whether or not one can estimate the next eigenvalue μ2(D ) has not yet been investigated for Dirac operators. Remark that in case of the Laplacian acting on functions of an Einstein spaceM 6= S, there are lower estimates for small eigenvalues depending on the minimum of the sectional curvature, s...
متن کاملDeformations of G-structures Part A: General Theory of Deformations
This paper is concerned with deformations of structures on manifolds. It is divided into two parts: Part A treats the question of defining a general theory of deformations which will generalize the theory in, e.g. [1 ], [7], and [10], while at the same time retaining some geometric or analytical significance. The second section, Part B, investigates in more detail the implications of our genera...
