π-paxtial charactersFor a group G,we produce upper and lower bounds for the sum of the entries of the Brauer character table of G and the projective indecomposable character table of G.When G is a π-s... 查看全部>>Xiaoyou ChenMark L.LewisHung P.Tong-Viet代数集刊:英文版...
This paper extends the well known Held-Karp's lower bound available for a single travelling salesman problem to the following multiple depot UAV routing problem (MDURP): Given a collection of UAVs that start at different depots, a set of terminals and destinations, the problem is to choose pa...

The nef cone of a projective variety Y is an important and often elusive invariant. In this paper we construct two polyhedral lower bounds and one polyhedral upper bound for the nef cone of Y using an embedding of Y into a toric variety. The lower bounds generalize the combinatorial descripti...
An intermediate theorem for the Fokker-Planck equation is presented for the first time from which lower bounds for the eigenvalues can be extracted. The same theorem can be applied to the master equation in detailed balance. We discuss as a first application the lower and upper bounds for the...
We propose lower and upper bounds for the KL divergence, which lead to a new approximation and interesting insights into previously proposed approximations. An application to the comparison of speaker models also shows how such approximations can be used to validate assumptions on the models. 展开 ...
We establish rigorous upper and lower bounds for the speed of pulled fronts with a cut-off. For all reaction terms of KPP type a simple analytic upper bound is given. The lower bounds however depend on details of the reaction term. For a small cut-off parameter the two leading order term...
German mathematician K. Weier-strass; they are basic for the rigorous exposition of the fundamentals of mathematical analysis. Analogous to the concept of upper and lower bounds for sets of numbers has been the introduction of the concepts of upper and lower bounds for any partially ordered sets...
Entanglement Rényi-α entropy is an entanglement measure. It reduces to the standard entanglement of formation when α tends to 1. We derive analytical lower and upper bounds for the entanglement Rényi-α entropy of arbitrary dimensional bipartite quan
Scala语言的高级特性*(了解概念、例子即可) (三)Upper Bounds与Lower Bounds 类型的上界和下界,是用来定义/规定类型变量的范围。它们的含义如下: 1.S <: T 这是类型上界的定义。也就是S必须是类型T的子类(或本身,自己也可以认为是自己的子类。 2.U >: T ...
