Harmonic surfaces in the Cayley plane
Nuno Correia, Rui Pacheco, Martin Svensson
We consider the twistor theory of nilconformal harmonic maps from a Riemann surface into the Cayley plane . By exhibiting this symmetric space…
Nonlinear Effects of Gravity in Cosmology
Johan Hansson, Jaime Dols Duxans, Martin Svensson
We consider some nonlinear effects of gravity in cosmology. Possible physically interesting consequences include: non-requirement of dark matter and dark energy, asymmetric gravita…
Continuous deformations of harmonic maps and their unitons
Alexandru Aleman, María J. Martín, Anna-Maria Persson +1
We consider harmonic maps on simply connected Riemann surfaces into the group of unitary matrices of order . It is known that a harmonic map with an associated a…
Harmonic morphisms from homogeneous spaces of positive curvature
Sigmundur Gudmundsson, Martin Svensson
We prove local existence of complex-valued harmonic morphisms from any Riemannian homogeneous spaces of positive curvature, except the Berger space Sp(2)/SU(2).
Harmonic morphisms from five-dimensional Lie groups
Sigmundur Gudmundsson
We consider 5-dimensional Lie groups with left-invariant Riemannian metrics. For such groups we give a partial classification of left-invariant conformal foliations with minimal le…
Harmonic morphisms from four dimensional Lie groups
Sigmundur Gudmundsson, Martin Svensson
We consider four dimensional Lie groups with left-invariant Riemannian metrics. For such groups we classify left-invariant conformal foliations with minimal leaves of codimension t…
