Homogeneity and h -homogeneity
Topology and its Applications, 2013 A topological space \(X\) is \textit{homogeneous} if each of its points can be carried to any other via a homeomorphism of the space; \(X\) is \textit{\(h\)-homogeneous} if it is homeomorphic to each of its nonempty clopen subspaces. The author investigates conditions under which these two notions are related for zero-dimensional spaces. The first main

Lorentzian homogeneous spaces admitting a homogeneous structure of type T1+T3
, 2005 We show that a Lorentzian homogeneous space admitting a homogeneous structure of type T1 + T3 is either a (locally) symmetric space or a singular homogeneous plane wave.Comment: 7 pages, Latex2e, a small note and a reference ...

Synthesis and investigation of physico-chemical properties of dicationic ionic liquids [PDF]
Royal Society Open Science, 2018 A series of dicationic ionic liquids (ILs) including [C4(MIM)2][PF6]2, [C5(MIM)2][PF6]2, [C6(MIM)2][PF6]2 and [C4(PYR)2][PF6]2 were synthesized. Their thermal stability and melting points were analysed.

Homogeneous time-invariant systems [PDF]
, 1999 It is well known that linear time-invariant (LTI) systems produce exponential outputs in response to exponential inputs. The purpose of this paper is to draw attention to the fact that the same result holds for the broader class of homogeneous time ...

Homogeneous Permutations [PDF]
The Electronic Journal of Combinatorics, 2002 There are just five Fraïssé classes of permutations (apart from the trivial class of permutations of a singleton set); these are the identity permutations, reversing permutations, composites (in either order) of these two classes, and all permutations. The paper also discusses infinite generalisations of permutations, and the connection with Fraïssé's ...
