Branching Rules for Splint Root Systems
نویسندگان
چکیده
A root system is splint if it a decomposition into union of two disjoint systems. Examples such systems arise naturally in studying embeddings reductive Lie subalgebras simple algebras. Given system, one can try to understand its branching rule. In this paper we discuss methods rules, and give precise formulas for specific cases, including the restriction functor from exceptional algebra $\mathfrak {g}_{2}$ {sl}_{3}$ .

Branching Rules for Satis ability
Recent experience suggests that branching algorithms are among the most attractive for solving propositional satissability problems. A key factor in their success is the rule they use to decide on which variable to branch next. We attempt to explain and improve the performance of branching rules with an empirical model-building approach. One model is based on the rationale given for the Jeroslo...
متن کامل2 00 4 Branching rules , Kostka - Foulkes polynomials and q - multiplicities in tensor product for the root systems
The Kostka-Foulkes polynomials K λ,μ(q) related to a root system φ can be defined as alternated sums running over the Weyl group associated to φ. By restricting these sums over the elements of the symmetric group when φ is of type Bn, Cn orDn, we obtain again a class K̃ φ λ,μ(q) of Kostka-Foulkes polynomials. When φ is of type Cn or Dn there exists a duality beetween these polynomials and some n...
متن کاملBranching rules revisited
Mixed integer programs are commonly solved with linear programming based branch-and-bound algorithms. The success of the algorithm strongly depends on the strategy used to select the variable to branch on. We present a new generalization called reliability branching of today’s state-of-the-art strong branching and pseudocost branching branching strategies for linear programming based branch-and...
متن کاملStable Branching Rules for Classical Symmetric Pairs
Given completely reducible representations, V and W of complex algebraic groups G and H respectively, together with an embedding H →֒ G, we let [V,W ] = dimHomH (W,V ) where V is regarded as a representation of H by restriction. If W is irreducible, then [V,W ] is the multiplicity of W in V . This number may of course be infinite if V or W is infinite dimensional. A description of the numbers [V...

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
