Let G= H⋉ K denote a semidirect product Lie group with Lie algebra g= h⊕ k, where k is an ideal and h is a subalgebra of the same dimension as k. There exist some natural split isomorphisms S with S2= ± Id on g: given any ...

We prove an existence result for local and global G-structure preserving affine immersions between affine manifolds. Several examples are discussed in the context of Riemannian and semi-Riemannian geometry, including the ...

Let X be a set. Let K(x, y) > 0 be a measure of the affinity between the data points x and y. We prove that K has the structure of a Newtonian potential K(x, y) = φ(d(x, y)) with φ decreasing and d a quasi-metric on X under ...

This paper attempts to provide an economic interpretation of the factors that drive the movements of interest rates of bonds of different maturities in a continuous-time no-arbitrage term structure model for Chile. The ...

We present here the results of a Density Functional Theory study of the relationships between electronic structure and peripheral benzodiazepine receptor affinity for a group of N,N-dialkyl-2-phenylindol-3-ylglyoxylamide ...

Halogenation of the aporphine alkaloid boldine at the 3-position leads to increased affinity for rat brain D1-like dopaminergic receptors with some selectivity over D2-like receptors. A series of 3-halogenated and ...
