Basing Point Pricing and Production Concentration

The Economic Journal, 1991
Basing point pricing is a delivered price system in which the price quoted for delivery of a commodity is the sum of the price quoted at a predetermined basing point plus the cost of transportation from the basing point to the point of delivery, whether or not the commodity is actually shipped from the basing point. Thus, a seller who is not located at

On the concentration of points of polynomial maps and applications

Mathematische Zeitschrift, 2011
This paper presents an asymptotic formula for the number of visible points on the curve \(f(x)\equiv y\pmod p\), where \(f\in\mathbb F_p[X]\) is a polynomial of degree \(d \geq 2\), and new achievements on the expansion of orbits in dynamical systems generated by nonlinear polynomials.

Two-point concentration in random geometric graphs

Combinatorica, 2008
Consider a sequence of independent identically distributed random variables \(X_n\) for \(n=1,2,\dots\) with a bounded density function in \(d\)-dimensional Euclidean space. A geometric graph \(G_n\) is defined on the first \(n\) random variables as vertices with edges between variables that are closer than a specified positive radius \(r=r(n)\). For \(

Hypercube Point Concentration Sampling Technique

2007
A new sampling technique referred to as the hypercube point concentration sampling technique is proposed. This sampling technique is based on the concepts of the Latin hypercube sampling technique and the point concentration method. In the proposed technique, first, the probability density function of the random variables is replaced by a sufficiently ...

Spectral concentration for dense point spectrum

1990
The degree of spectral concentration at an eigenvalue λ0 embedded in a dense point spectrum is shown to depend on the extent to which λ0 is approximated by other eigenvalues whose eigenfunctions have appreciable overlap with the eigenvectors of λ0.

Number of points of discontinuity of concentration functions

Mathematical Notes of the Academy of Sciences of the USSR, 1984
Let X be a random variable that takes a finite number of values, say n, Q the concentration function of X extended for negative values by zero, and N(X,n) the number of discontinuity points of Q. Then \(N(X,n)=n\) for \(n\leq 2\), 3\(\leq N(X,3)\leq 4\), \(4\leq N(X,n)\leq n(n-1)/2+1\) for \(n\geq 4\), and all estimates are sharp.

Why does charge concentrate on points?

Physics Education, 1989
A pointed conductor is modelled by a sequence of touching spheres. The requirement that the electric field strength should vanish between them yields an explanation of charge concentration that appears more realistic than the usual textbook argument.

Identification of Concentration Points, Subconformal Case

1999
In order to identify the possible concentration points of low energy limits we expand the supremum (1.2) with respect to ɛ to second order. The complete strategy has been explained in the introduction.
