On generalized Cauchy Riemann equations on manifolds. (English) Zbl 0575.32028

This is a research announcement, without proofs, of results concerning a generalization of \(\partial\), \({\bar \partial}\) on a Riemann surface to higher dimensional manifolds. The point is that the generalization applies to other than complex manifolds. The concept that replaces ”almost complex structure” is splitting of a vector-valued de Rham sequence.
The authors give several nice applications of their ideas which provide good motivation for the work.
