Kähler potential
A Kähler potential is a real-valued function defined on some coordinate patch of aHermitean manifold such that the metric of the manifold is given by the expression
It turns out that, for every Káhler manifold, there will exist a coordinate neighborhood of anygiven point in which the metric can be expresses in terms of a potential this way.
As an elementary example of a Kähler potential, we may consider . This potential gives rise to the flat metric .
Kähler potentials have applications in physics. For example, this function relates to the motion of certain subatomic particles called gauginos.
