Abstract: A work in progress with Nattalie Tammam states that in arithmetic homogeneous spaces a divergent diagonal trajectory of the maximal possible dimension is divergent due to finite algebraic reasons.
We will discuss the geometric part of the proof (in the space of lattices), explain the geometry of the cusp, and how to use this information.
