Completions of Quantum Coordinate Rings
Given an iterated skew polynomial ring C[y1; τ1, δ1] . . . [yn; τn, δn] over a complete local ring C with maximal ideal m, we prove, under suitable assumptions, that the completion at the ideal m+ 〈y1, y2, . . . , yn〉 is an iterated skew power series ring. When C is a field, this completion is a local, noetherian, Auslander regular domain with Krull, classical Krull and global dimension all equ...
متن کاملTime: A Coordinate for Web Site Modelling
The adoption of high level models has been advocated by many authors as instrumental in Web site development as a strong support to both design and maintenance. We will discuss how the specification of Web sites at the logical level can greatly benefit from the introduction of specific features for the representation of time, which could also support the notions of versions and editions of obje...
متن کاملFreeness of the Quantum Coordinate Algebras
The main purpose of this note is to prove that the quantum coordinate algebra A[U ] is free over the ring A = Z[v, v−1]. In [L1], Lusztig defined the quantum coordinate algebra over Q[v, v−1] and prove that it is free as Q[v, v−1]-module. In [APW], Andersen, Polo, and Wen defined the quantum coordinate algebra over the ring A(p,v−1) and proved that the coordinate algebra is free. The main idea ...
متن کاملQuantum mechanics with coordinate-dependent mass
We study a motion of quantum particles, whose properties depend on one coordinate so that they can move freely in the perpendicular direction. A rotationally-symmetric Hamiltonian is derived and applied to study a general interface formed between two semiconductors. We predict a new type of electron states, localized at the interface. They appear whenever the two bulk dispersions intersect. The...
متن کاملA Quantum Evolutionary Algorithm for the Vehicle Routing Problem with Single-sided Time Window Setting
Customer service level is of prime importance in today competitive world and has various dimensions with delivery quality being one of the most important ones. Delivery quality has several parameters such as deliver time window options, time window size, etc. In this paper we focus on one of these parameters, namely time window setting. It has a direct impact upon customer satisfaction and busi...
