Consider the following regularity condition (Pn): every projectivity fixing n points is the identity. It was known that if the subgroup Π of all proper projectivities satisfies (P3) the plane must be Miquelian. The author shows that this is true even if Π satisfies (P4).

Abstract
Consider the following regularity condition (Pn): every projectivity fixing n points is the identity. It was known that if the subgroup Π of all proper projectivities satisfies (P3) the plane must be Miquelian. The author shows that this is true even if Π satisfies (P4).File in questo prodotto:
