Introduction to , Geometryalgebraic structure in 7 dimensions that is the pointwise model for . geometry, using the octonions. The basics of .-structures are introduced, from a Riemannian geometric point of view, including a discussion of the torsion and its relation to curvature for a general .-structure, as well as the con

Constructions of Compact ,-Holonomy Manifoldssolutions of singularities of appropriately chosen 7-dimensional orbifolds, with the help of asymptotically locally Euclidean spaces. Another method uses the gluing of two asymptotically cylindrical pieces and requires a certain matching condition for their cross-sections ‘at infinity’.

Distinguished ,-Structures on Solvmanifoldsys between these concepts in the context of left-invariant .-structures on solvable Lie groups. Also, some Ricci pinching properties of .-structures on solvmanifolds are obtained, in terms of the extremal values and points of the functional ., .. Many natural open problems have been included.
