Hi, everyone: I am doing some reading on the Frolicher Spec Seq. and I am trying to understand better the Kahler mflds. Specifically: What is meant by the fact that the complex structure, symplectic structure and Riemannian structure (from being a C^oo mfld.) are "mutually compatible"? I read this in both Griffiths and Harris and in the Wiki page. I realized I chose a handle that does not have a good abbreviation. Choices are: What, What Would, What Would Gauss, Do, None of them too good. Anyway, chronic burnout is getting to me. Thanks for any answer or suggestions for refs.
