Query: Real structures on horospherical varieties   We study the equivariant real structures on complex horospherical varieties,
generalizing classical results known for toric varieties and flag varieties. In
particular, we obtain a necessary and sufficient condition for the existence of
such real structures and determine the number of equivalence classes. We then
apply our results to classify the equivariant real structures on smooth
projective horospherical varieties of Picard rank 1.
