In many point-line geometries, to cover all points except one, more lines are needed than to cover all points. Bounds can be given by looking at the dimension of the space of functions induced by polynomials of bounded degree.

In this paper, we investigate even-order linear difference equations and their criticality. However, restrict our attention only to several special cases of the general Sturm–Liouville equation. We wish on such a possible converse known theorem. This theorem holds for second-order as an equivalence; however, one implication is equations. First, show in sense term Later, upper bound criticality ...
