WebHelly-Type Theorems and Generalized Linear Programming* N. Amenta Computer Science, University of California, Berkeley, CA 94720, USA and The Geometry Center, Minneapolis, MN 55454, USA Abstract. Recent combinatorial algorithms for linear programming can also be applied to certain ... WebIn probability theory, the Helly–Bray theorem relates the weak convergence of cumulative distribution functions to the convergence of expectations of certain measurable functions. It is named after Eduard Helly and Hubert Evelyn Bray. Let F and F 1, F 2, ... be cumulative distribution functions on the real line.

Intuitively, the reason the theorem holds is that bounded continuous functions can be approximated closely by sums of continuous fialmost-stepfl functions, and the expectations of fialmost stepfl functions closely approximate points of CDF™s.
