We define a cotangency set (in the projective plane over any field) to be a set of points that satisfy two conditions (A) and (B). The main result says that a cotangency set can never contain a quadrangle. A number of profound-sounding consequences involving Hermitian curves are really observations that follow quickly from the theorem by way of elementary arguments. |
