A combinatorial property of Bernstein-Gelfand-Gelfand resolutions of unitary highest weight modules.
… of consecutive parabolic Verma modules in the Bernstein-Gelfand-Gelfand-Lepowsky resolution of the trivial representation is a single root. We show that an analogous property holds for all unitary representations of simply laced type. Specifically, the difference between consecutive highest …
