In this note we investigate the $(E)$-index and the $(E)$-nullity of vacuum solutions from the two-torus into the two sphere.

Ricci-flat and Einstein pseudoriemannian nilmanifolds
Abstract This is partly an expository paper, where the authors’ work on pseudoriemannian Einstein metrics on nilpotent Lie groups is reviewed. A new criterion is given for the existence of a diagonal


Dressing orbits of harmonic maps
We study the harmonic map equations for maps of a Riemann surface into a Riemannian symmetric space of compact type from the point of view of soliton theory. There is a well-known dressing action of
Harmonic tori in symmetric spaces and commuting Hamiltonian systems on loop algebras
Much of the qualitative behaviour of the problem can be seen in embryo form in the simplest possible case: that of harmonic maps of a compact Riemann surface M into S. If M is the Riemann sphere, all

When a person thinks of algebra, they typically think of a process used to solve polynomial equations. Modern Number theory has evolved through several stages in the past two millennia. Notions of
