Query: Nonzero degree tangential maps between dual symmetric spaces   We construct a tangential map from a locally symmetric space of noncompact
type to its dual compact type twin. By comparing the induced map in cohomology
to a map defined by Matsushima, we conclude that in the equal rank case the map
has a nonzero degree.
