in this paper, we introduce a notion of property (t) for a c∗-dynamical system (a, g, α) consisting of a unital c∗-algebra a,a locally compact group g, and an action α on a. as a result,we show that if a has strong property (t) and g has kazhdan’sproperty (t), then the triple (a, g, α) has property (t).

This article documents two programmatic comments regarding testing graph properties, which I made during the Dagstuhl workshop on Sublinear-Time Algorithms (July 2005). The first comment advocates paying more attention to the dependence of the tester’s complexity on the proximity parameter. The second comment advocates paying more attention to the question of testing general graphs (rather than...

We show that in the bounded degree model for graph property testing, adaptivity is essential. An algorithm is non-adaptive if it makes all queries to the input before receiving any answers. We call a property non-trivial if it does not depend only on the degree distribution of the nodes. We show that every tester for a non-trivial property that makes o ( √ n/d) queries to the input graph on n v...

Abstract Probate inventories helped to support the established social and economic order in colonial Jamaica. These documents were part of legal process winding up an estate after a death presented account personal possessions that had belonged decedent. They facilitated transfer property heirs identified those parts available for repayment debts. The contain lists enslaved people, representing...

Recent global developments in the regulation of trade and intellectual property rights threaten to hinder the access of populations in developing countries to essential drugs. The authors argue for state intervention in the health and pharmaceutical markets in order to guarantee equitable access to these products.
