查询词典 representation theory

Based on the relationship between the structure and function, a lot of research have been performed on predicting base-pair which is indispensable to the RNA three-dimensional strcutrue. The tools and methods in Combinatorics and Statistics will play important roles in studying linear sequences of biomolocular units . Similarly, we can present the geometric representation of biological sequences and structures. So the genometric topology and group theory are important also.

The family of quaternions plays a role in quantum physics, geostatics, control theory and peg-top technology. It is important to know and research quaternions as the development of quaternions. Thus the real representation of quaternion matrices has been appeared.

近年来，四元数矩阵在刚体力学，量子力学，控制理论和陀螺技术中的应用日趋重要和广泛，随着上述四元数力学的不断发展，对四元数矩阵的进一步认识和研究就显得越来越重要。

Aimed to two major problems: one is not decidable and the other is no clear semantics. We construct a framework with explicit representation and formal semantics of goalsgoal description logics, which integrates two types of goals: declarative goals and procedural goals into one concept based on description logics. In addition, the goal plan is defined and analyzed, and some reasoning problems, such as goal consistency and goal satisfiability, are discussed. Contrary to traditional ways of goal description, GDLs can bridge the gap between theory and practice in a natural way.

针对传统的目标描述中存在的不可判定性以及没有清晰的语义等问题，在描述逻辑(description logics，DLs)上，将宣称型和过程型2种类型的目标描述有机地整合在一起，从而构建了具有清晰语义与可判定性的形式化框架--目标描述逻辑(goal description logics， GDLs)，在此基础上，定义了该框架下有关规划规则；建立了可用于判定目标一致性、目标可满足性的方法，与传统的目标描述方法相比，目标描述逻辑为主体领域模型提供了一种更有力的形式化工具，同时为智能主体的模型和设计提供了很好的理论工具。
