This paper is concerned with joint distributions, joint moments, and joint renewal functions in a stationary point process. The random variables considered are (a) the numbers of events in adjacent ...

Potential energy surfaces are the central concept in understanding the assembly of molecules; atoms form molecules via covalent bonds with structures defined by the stationary points of the surfaces.

It is sometimes desired to fit a second degree polynomial E(y∣ x) = α + β x + γ x 2 to a set of data so that its stationary point will fall in a given region. Methods are shown to calculate a, b, c, ...
