The Metric Projection

2001
In this chapter we shall study the various properties of the metric projection onto a convex Chebyshev set K. It is always true that Pk is nonexpansive and, if K is a subspace, even linear. There are a substantial number of useful properties that Pk possesses when K is a subspace or a convex cone.

A Characterization of Projective Metric Spaces

Canadian Mathematical Bulletin, 1986
AbstractA projective metric space is a pappian projective space together with a quadric and a certain equivalence relation on the pairs of those points which do not belong to the quadric. This equivalence relation is defined by means of the corresponding quadratic form and satisfies a condition which is a projective version of Miquel's theorem.

Metric Projections and Polyhedral Spaces

Set-Valued Analysis, 2006
Let \(X\) be a Banach space and \(Y\) a proximinal subspace of \(X\). The metric projection \(P_Y\) onto \(Y\) is called Hausdorff lower semi-continuous at \(x_0\in X\) if for every \(\epsilon >0\) there exists \(\delta=\delta(\epsilon)>0\) such that \(B(z,\epsilon)\cap P_Y(x)\neq \emptyset\) for every \(z\in P_Y(x_0)\) and every \(x\in B(x_0,\delta) =

Projective and Metric Geometry

The Annals of Mathematics, 1904
THE passage from synthetic projective to metric geometry is seldom made in a systematic and satisfactory manner. Those whose point of view is pure synthetic geometry, for example Reye or B6ger or Enriques, assume the metric geometry as given and confine their attention to interpreting it in terms of projective relations.

Project Management Metrics [PDF]

Oeconomics of Knowledge, 2010
Metrics and indicators used for the evaluation of the IT projects management have the advantage of providing rigorous details about the required effort and the boundaries of the IT deliverables. There are some disadvantages, as well, due to the fact the input data contains errors and the value of metrics depends on the quality of data used in models.
