Abstract

Let L be a simply-connected simple connected algebraic group over a number field F, and H be a semisimple absolutely maximal connected F-subgroup of L. Let \(\Delta (H)\) be the image of H diagonally embedded in \(L^n\). Under a cohomological condition, we prove an asymptotic formula for the number of rational points of bounded height on projective equivariant compactifications of \(\Delta (H)\backslash L^n\) with respect to a balanced line bundle.
