A note on vague graphs

In this paper, we introduce the notions of product vague graph, balanced product vague graph, irregularity and total irregularity of any irregular vague graphs and some results are presented. Also, density and balanced irregular vague graphs are discussed and some of their properties are established. Finally we give an application of vague digraphs.

A note on lifting projections

Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain  mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...

Protecting Antiquities: A Role for Long-Term Leases?∗

140 countries have adopted bans on exports of antiquities, in part because these are seen as needed to protect cultural heritage for future generations. However, if enforcement is imperfect, export bans may be counterproductive, spurring the growth of a black market trade which can damage objects and obscure the archaeological record. We argue that allowing fixed-duration, long-term leases of a...
