Simultaneously bounded and dense orbits for two diagonal flows

Let d≥3d\geq 3, let Xd=SLd(R)/SLd(Z)X_d=\mathrm{SL}_d(\mathbb{R})/\mathrm{SL}_d(\mathbb{Z}), and let v1≠v2v^1\ne v^2 be two nonzero vectors in the diagonal subalgebra of sld(R)\mathfrak{sl}_d(\mathbb{R}). Write gti=exp⁡(tvi)g_t^i=\exp(tv^i) for i=1,2i=1,2 and t∈Rt\in\mathbb{R}. Ray conjecture. The set

B({gt1}t≥0)∩D({gt2}t≥0)B(\{g_t^1\}_{t\geq 0})\cap D(\{g_t^2\}_{t\geq 0})

has full Hausdorff dimension in XdX_d. This extends the known SL3\mathrm{SL}_3 result and is presented as an open strengthening of the paper's simultaneous bounded-and-dense orbit results.
