General Connections, Exponential Maps, and Second-order Differential Equations

Autor: Del Riego, L., Parker, Phillip. E.

The main purpose of this article is to introduce a comprehensive, unified theory of the geometry of all connections. We show that one can study a connection via a certain, closely associated second-order differential equation. One of the most importa

Pseudoconvex and Disprisoning Homogeneous Sprays

Autor: Del Riego, L., Parker, P. E.

The pseudoconvex and disprisoning conditions for geodesics of linear connections are extended to the solution curves of general homogeneous sprays. The main result is that pseudoconvexity and disprisonment are jointly stable in the fine topology on t

In this work we show evidence of mother-to-offspring transmission in a transgenic mouse line expressing bovine PrP (boTg) experimentally infected by intracerebral administration of bovine spongiform encephalopathy (BSE) prions. PrP res was detected i
