Abstract

The space SL(2,R)×SL(2,R)SL(2,\mathbb{R})\times SL(2,\mathbb{R}) admits a natural homogeneous pseudo-Riemannian nearly Kaehler structure. We investigate almost complex surfaces in this space. In particular we obtain a complete classification of the totally geodesic almost complex surfaces and of the almost complex surfaces with parallel second fundamental form.
