48 results for Fueter theorem

We prove that a sequence of Fueter sections of a bundle of compact hyperkahler manifolds X\mathfrak X over a 33-manifold MM with bounded energy converges (after passing to a subsequence) outside a 11-dimensional closed rectifiable subset SMS \subset M. The non-compactness along SS has two sources: (1) Bubbling-off…

We prove an existence theorem for Spin(7)-instantons, which are highly concentrated near a Cayley submanifold; thus giving a partial converse to Tian's foundational compactness theorem. As an application, we show how to construct Spin(7)-instantons on Spin(7)-manifolds with suitable local K3 Cayley fibrations. This rec…

We find Weitzenböck formula for the Fueter-Dirac operator which controls the infinitesimal deformations of an associative submanifold in a 77--manifold with a G2G_2--structure. We establish a vanishing theorem to conclude rigidity under some positivity assumptions on curvature, which are particularly mild in the nearl…

We give an example of a homogeneous reflexive sheaf over C3\mathbb{C}^3 which admits a non-conical Hermitian Yang-Mills connection. This is expected to model bubbling phenomenon along complex codimension 2 submanifolds when the Fueter section takes zero value.

This is the first part in a series of three articles in which are studied the domains of monogenicity for the nn-Cauchy-Fueter operator. Using the twistor theory, we will in this article show that for a given open subset UU of Qn\mathbb{Q}^n, there is an open subset H(U)\mathcal{H}(U), called the monogenic hull of UU,…
