Surfaces in self-dual Einstein manifolds and their twistor lifts

Abstract: In this note, we consider surfaces in self-dual Einstein manifolds whose twistor lifts are harmonic sections. In particular, we state the stability of the twistor lifts as harmonic sections and determine such surfaces of genus zero. This paper is a short survey of our previous results in Hasegawa (2007, 2009, 2011) . [Copyright &y& Elsevier]
