Back in 1974, he tested what he thought was an easy example — a Harvard study by the eminent pollster Samuel Stouffer, conducted in the fifties during the height of McCarthyism.
We give an easy example of a partial metric space, which is not a metric space, and a selfmap in it which is a quasicontraction and not a contraction.
PARKER: Perhaps it's not fair to prognosticate about Elizabeth Berkley, but it's an easy example in a way.
Indeed, the partial metric space ( Q ∩ [ 0, ∞ ), p ), where ℚ denotes the set of rational numbers and the partial metric p is given by p ( x, y ) = max { x, y } for all x, y ∈ X, provides an easy example of a 0-complete partial metric space which is not complete.
We will provide an easy example of such a situation in the following.
We present an easy example to show that in general a b-metric need not be a metric.
Here, we present an easy example to show that in general, a b-metric need not necessarily be a metric (see also [[28], p.264]).
First we give an easy example which shows that it has a negative answer in general, but the answer is positive whenever the weaker Meir-Keeler function is non-decreasing as Theorem 5 below shows.
But rather than criticizing these practices as examples of an autocracy run amok, Islamophobes cite Saudi Arabia as an easy example to justify views like "Fear of Muslims is RATIONAL".
As an easy example of how this plays out in an already-familiar situation, suppose E = R m, the graph with one vertex and m loops.
