Synthesis, Structures, and Properties of Dehydrobiphenyleno[12]Annulenes: Carbon‐Rich Compounds Comprising Two Different Antiaromatic Units

Chemistry – An Asian Journal, EarlyView.
Carbon‐rich compounds dehydrobiphenyleno[12]annulenes (DBP[12]As) comprising antiaromatic four‐membered rings (4MR) and 12‐membered ring (12MR) were synthesized and characterized. DBP[12]As feature high HOMO energy levels and narrow HOMO‐LUMO gaps. The 4MRs have stronger antiaromatic character than the 12MR in DBP[12]As. Abstract In this work we report

Common Fixed Points for Maps on Topological Vector Space Valued Cone Metric Spaces

International Journal of Mathematics and Mathematical Sciences, 2009
We introduced a notion of topological vector space valued cone metric space and obtained some common fixed point results. Our results generalize some recent results in the literature.

On Irresolute Topological Vector Spaces-II

, 2016
In this paper, our focus is to investigate the notion of irresolute topological vector spaces. Irresolute topological vector spaces are defined by using semi open sets and irresolute mappings.

Topological photonics

Nature Photonics, 2014
Applying the mathematical concept of topology to the wave-vector space of photonics yields exciting opportunities for creating new states of light with useful properties such as unidirectional propagation and the ability to flow around imperfections. The
