Book 2000subspaces of a projective geometry G. If x E GE, then g(x) := (E V x) n F (where E V x is the subspace generated by E U {x}) is a unique point of F, i.e. one obtains a map 9 : GE -4 F. As special case, if E = {z} is a singleton and F a hyperplane with z tf. F, then g: G{z} -4 F is the projection with center z of G onto F.

thing new to be added. But it seems that there exists no book on projective geometry which provides a systematic treatment of morphisms. We intend to fill this gap. It is in this sense that the present monograph can be called modern. The reason why morphisms have not been studied much earlier is pro

High Auditory Time Resolution in Bottlenose Dolphins Is Effective Protection Against Reverberationf . sonar clicks can provide extremely good protection against reverberation. However, the auditory time resolution of . is widely believed to be ∼300 µs (e.g., Au 1993; Supin et al. 2001) despite abundant behavioral data indicating that the auditory time resolution is as high as the theoretical tim
