We introduce a new class of connected solvable Lie groups called -group. Namely a -group is a connected solvable Lie group with center such that for some in the Lie algebra of , the symplectic for on given by is nondegenerate. Moreover, apart form some technical requirements, it will be proved that a connected unimodular Lie group with center , such that the center of is finite, has discrete series if and only if may be written as , , where is a -group with...

We give an explicit recollement for a cocomplete abelian category and its colimit category. We obtain some applications on Leavitt path algebras, derived equivalences and -groups.

An invertible linear map on a Lie algebra is called a triple automorphism of it if for . Let be a finite-dimensional simple Lie algebra of rank defined over an algebraically closed field of characteristic zero, an arbitrary parabolic subalgebra of . It is shown in this paper that an invertible linear map on is a triple automorphism if and only if either itself is an automorphism of or it is the composition of an automorphism of and an extremal map of order . ...

[For the entire collection see Zbl 0742.00067.]The author formulates several theorems about invariant orders in Lie groups (without proofs). The main theorem: a simply connected Lie group admits a continuous invariant order if and only if its Lie algebra contains a pointed invariant cone. V. M. Gichev has proved this theorem for solvable simply connected Lie groups (1989). If is solvable and simply connected then all pointed invariant cones in are global in (a Lie wedge ...
