Big Subgroups of Automorphism Groups of Doubly Homogeneous ChainsWe seek new maximal subgroups of the group .(R) of order-automorphisms of the real line R. This leads us to investigate supplements of the normal subgroup B(R) consisting of the elements of bounded support. (A . of . is a subgroup . of . such that . = . R could be replaced by the rational line Q, and often by any doubly homogeneous chain Ω.

Isotone Projection Conesconverse is true. Their methods are somewhat complicated and depend on a number of auxiliary concepts. In this note we show that with a slight modification of the definition of correctness the converse is true without the restriction to finite dimensionality. At the same time we give more transparent proofs of their necessity results.

Natural Partial Orders on Division Rings with Involution, b ∈ ., and where II is the strictly positive cone for an additive partial group order on (., +). The involution defines several natural multiplicative subgroups . ⊂ . 0, and the positive cones are defined by II = .., where .. consists of all the finite sums of elements of ..

Torsion Classes of Vector Latticesoup or a conditionally laterally complete . -group, then . is a vector lattice if and only if each . is a vector lattice, which is true if and only if each ., with . a special element, is a vector lattice.
