Take the setting of RW2, except that the two parallel lines, when examined with strong lenses, reveal a periodic structure. The concepts it uses connects it to such diverse fields as complex analysis, topology and number theory. For that reason, while I would recommend this book to a student who is new to the area, the first seven sections of this book will not be all that useful to people who are already familiar with the field.

Factorizations of this type occur quite generally (see the Stein factorization theorem (8. ν = 19: we have a map ψ: Γ3 → P19 .6) tells us that all the fibres have dimension ≥ 1. and the set where the dimension is > 1 is a proper closed subset.

Geometry proofs are probably the most dreaded assignment in high school mathematics because they force you to break down something you may understand intuitively into a logical series of steps.
