There's a specific fascination whilst it seems that disjoint components of arithmetic prove to have a significant connection to one another. the most aim of this ebook is to supply a mostly self-contained, in-depth account of the linkage among nonassociative algebra and projective planes, with specific emphasis on octonion planes. There are a number of new effects and plenty of, if now not such a lot, of the proofs are new. the improvement can be available to so much graduate scholars and may supply them introductions to 2 components that are frequently referenced yet rarely taught. at the geometric part, the publication introduces coordinates in projective planes and relates coordinate houses to transitivity houses of definite automorphisms and to configuration stipulations. It additionally classifies higher-dimensional geometries and determines their automorphisms. the outstanding octonion aircraft is studied intimately in a geometrical context that permits nondivision coordinates. An axiomatic model of that context can also be supplied. eventually, a few connections of nonassociative algebra to different geometries, together with constructions, are defined. at the algebraic aspect, uncomplicated homes of other algebras are derived, together with the type of other department jewelry. As instruments for the learn of the geometries, an axiomatic improvement of measurement, the fundamentals of quadratic kinds, a remedy of homogeneous maps and their polarizations, and a examine of norm varieties on hermitian matrices over composition algebras are incorporated.
