For a given minimal surface in the n-sphere, two ways to construct a minimal surface in the m-sphere are given. One way constructs a minimal immersion. The other way constructs a minimal immersion which may have branch points. The branch points oc...
The aim of this paper is to investigate a new link between integrable systems and minimal surface theory. The dressing operation uses the associated family of flat connections of a harmonic map to construct new harmonic maps. Since a minimal surfa...

Att∗-bundle is constructed by aharmonicmap from aRiemannsurface into an n-dimensional sphere. This tt∗-bundle is a high-dimensional analogue of a quaternionic line bundle with a Willmore connection. For the construction, a flat connection is decom...
We factorize a super-conformal map. This factorization connects a super-conformal map with a holomorphic map. Then we obtain the Schwarz–Pick theorem for super-conformal maps. Then we define a distance on the image of a super-conformal map.
In this talk, we take up two classes of conformal maps and apply the canonical factorization. One is constrained Willmore surfaces and the other is minimal surfaces. A factor of a canonical factorization for a conformal map provides a canonical li...

A minimal surface in Euclidean space is a Willmore surface. A gauss map of a minimal surface and a conformal Gauss map of a Willmore surface are harmonic maps. Simple factor dressing of the Gauss map gives a new conformal harmonic map and that of ...
The Gauss map of a constant mean curvature surface in the Euclidean space is a harmonic map. Theory of constant non-zero mean curvature surfaces is associated with theory of harmonic maps from a surface to the two-dimensional sphere. Dressing is a...

A network partner of the m:iv minimal surfaces: integrable systems and visualisation.
An international research group funded by The Leverhulme Trust.
Led by Dr Katrin Leschke at the University of Leicester, Department of Mathematics; m:iv brings together researchers at five international institutions to work on the study of minimal surfaces: combining the expertise of the network partners in the areas of visualisation, minimal surfaces and integrable systems will allow new approaches in this research area. The network will run a series of seminars, ranging from introductory presentations to detailed talks on specialised results. The seminar series will develop the necessary foundations for the research whilst computer experiments are undertaken. Extended research visits each year will take place between network partners. In addition to the seminar series and research visits, the network will run a programme of workshops, hosted in turn by each network partner highlighting their area of research, with the final workshop taking place at Leicester, where the various strands will be linked together.
