Sebestyén Moment Problem: the Multi-dimensional Case
Given a family {hn}n∈ZΩ+ of vectors in a Hilbert space H we characterize the existence of a family of commuting contractions T = {Tω}w∈Ω on H having regular dilation and such that hn = T h0, n ∈ Z+. The theorem is a multi-dimensional analogue for some well-known operator moment problems due to Sebestyén in case |Ω| = 1 or, recently, to Găvruţă and Păunescu in case |Ω| = 2. Let H be a complex Hi...
متن کاملTruncated Moment Problem versus Moment Problem 3
It is shown that the truncated multidimensional moment problem is more general than the full multidimensional moment problem.
متن کاملA simple approach to the two-dimensional guillotine cutting stock problem
Cutting stock problems are within knapsack optimization problems and are considered as a non-deterministic polynomial-time (NP)-hard problem. In this paper, two-dimensional cutting stock problems were presented in which items and stocks were rectangular and cuttings were guillotine. First, a new, practical, rapid, and heuristic method was proposed for such problems. Then, the ...
متن کاملA Comparative Study of Exact Algorithms for the Two Dimensional Strip Packing Problem
In this paper we consider a two dimensional strip packing problem. The problem consists of packing a set of rectangular items in one strip of width W and infinite height. They must be packed without overlapping, parallel to the edge of the strip and we assume that the items are oriented, i.e. they cannot be rotated. To solve this problem, we use three exact methods: a branch and bound method, a...
متن کاملA two-dimensional problem of revenue maximization
We consider the problem of finding the mechanism that maximizes the revenue of a seller of multiple objects. This problem turns out to be significantlymore complex than the casewhere there is only a single object (which was solved by Myerson, 1981). The analysis is difficult even in the simplest case studied here, where there are two exclusive objects and a single buyer, with valuations uniform...
