چکیده

Let (Ω,F,P) be a probability space and L0(F) the algebra of equivalence classes real-valued random variables defined on (Ω,F,P). A left module M over (briefly, an L0(F)-module) is said to regular if x=y for any given two elements x y in such that there exists countable partition {An,n∈N} Ω F I˜An⋅x=I˜An⋅y each n∈N, where IAn characteristic function An I˜An its class. The purpose this paper establish fundamental theorem affine geometry L0(F)-modules: let V V′ L0(F)-modules contains free L0(F)-submodule rank 2, T:V→V′ stable invertible maps L0-line segment segment, then T must L0-affine.

Fundamental Theorem of Geometry without the 1-to-1 Assumption

It is proved that any mapping of an n-dimensional affine space over a division ring D onto itself which maps every line into a line is semiaffine, if n ∈ {2, 3, . . . } and D 6= Z2. This result seems to be new even for the real affine spaces. Some further generalizations are also given. The paper is self-contained, modulo some basic terms and elementary facts concerning linear spaces and also –...
