Almost complex manifolds with small Nijenhuis tensor

Abstract

We give several explicit examples of compact manifolds with a 11-parameter family of almost complex structures having arbitrarily small Nijenhuis tensor in the C0C^0-norm. The 44-dimensional examples possess no complex structure, whereas the 66-dimensional example does not possesses a left invariant complex structure, and whether it possesses a complex structure appears to be unknown.
