WebApr 1, 2024 · Observe that τ 1 ( H) = τ ( H). We can then generalise Ryser's Conjecture (in the intersecting case) by asking for the maximum of τ s ( H) over all ( r, t) -graphs. If s ≤ t, then, since every pair of edges intersects in at least t vertices, any edge e ∈ E ( H) is an s -cover, and so we always have τ s ( H) ≤ r.
