proved by András Gyárfás. The inequality is sharp: Let Hr- be the truncated projective plane of order r – 1. Then ν(Hr-) = 1 since every two hyperedges intersect...

In geometry, the truncated square tiling is a semiregular tiling by regular polygons of the Euclidean plane with one square and two octagons on each vertex...

In projective geometry, a cylinder is simply a cone whose apex (vertex) lies on the plane at infinity. If the cone is a quadratic cone, the plane at infinity...
