We prove that for a real analytic generic submanifold of whose Levi-form has constant rank, the tangential -system is non-solvable in degrees equal to the numbers of positive and negative Levi-eigenvalues. This was already proved in [1] in case the Levi-form is non-degenerate (with non-necessarily real analytic). We refer to our forthcoming paper [7] for more extensive proofs.
Si prova che per una sottovarietà analitica reale generica di la cui forma di Levi ha rango costante, il complesso tangenziale è non risolubile nei gradi corrispondenti ai numeri di autovalori positivi e negativi. Per forme non-degeneri il risultato era già stato stabilito in [1] (senza l’ipotesi che sia analitica reale).
