Eisenbahn-Bau- und BetriebsordnungWe study the problem, suggested by Singer in [.], and consisting in determining a notion of “local cohomology” adequate to deal with the problem of locality in those approaches to local anomalies based on the Atiyah–Singer index theorem.

https://doi.org/10.1007/978-3-642-91461-4It is proved that Parton-Piccinni’s expression . of the canonical 8-form on a manifold with holonomy group . is not trivial, by using the properties of the octonions.

Local Structure of Self-Dual Gradient Yamabe Solitons,We analyze the underlying structure of a pseudo-Riemannian manifold admitting a gradient Yamabe soliton. Special attention is paid to neutral signature, where a description of self-dual gradient Yamabe solitons is obtained.

The Prescribed Curvature Problem in Low Dimension,We describe some recent results concerning the inverse curvature problem, that is, the existence and description of metrics with prescribed curvature, focusing on the low-dimensional homogeneous cases.
