The topics include isometries in Euclidean vector spaces and their classification in Rn; the conic sections in the Euclidean plane; linear fractional transformations and planar hyperbolic geometry; finite probability theory and Bayesian analysis; and Boolean lattices, Boolean algebras, and Stone's theorem.

For collimated beam, [5] presents an alternative GO shaping technique based on the representation of the reflector generatrices by concatenated local conic sections. There, the authors employ rectangular coordinates to describe the local conic sections representing the reflectors' generatrices, leading to a set of nonlinear algebraic equations.
