Chapter 3 Infinite Groups
نویسنده
چکیده
• Rotational invariance, SO(3). Here we can rotate through an arbitrary angle specified by a continuous parameter θ, restricted to some finite range, say [0, 2π). There are a infinite continuum of possible values of θ, even though its range is limited. There are also two continuous parameters necessary to specify the direction about which this rotation is to take place. This is a three-parameter group.

the Degree of Doctor of Philosophy of the University of London Representations at a Root of Unity of q - Oscillators and Quantum Kac - Moody Algebras
The subject of this thesis is quantum groups and quantum algebras at a root of unity. After an introductory chapter, I set up my notation in chapter 2. The rest of the thesis is presented in three parts. In part I, quantum matrix groups and quantum enveloping algebras are discussed. In chapter 3, I present two well-known 2 × 2 matrix quantum groups, including their coaction on the quantum plane...
متن کاملOverlap-Free Words and Generalizations
The study of combinatorics on words dates back at least to the beginning of the 20 century and the work of Axel Thue. Thue was the first to give an example of an infinite word over a three letter alphabet that contains no squares (identical adjacent blocks) xx. This result was eventually used to solve some longstanding open problems in algebra and has remarkable connections to other areas of ma...
متن کاملSome Finite and Discrete Groups
We have have encountered several finite groups in the previous chapter: the cyclic group Zn, the symmetric group Sn, and its subgroup the alternating group An. The properties of these groups will be elaborated in this chapter. We will also discuss three other groups obtained by incorporating ‘reflections’ into Zn, the dihedral group Dn, the generalized quaterion group Qn, and the dicyclic group...

This is a preliminary " manuscript " version of the text published in the journal " Algebras, Groups and Geometries " by the independent Editor Prof. Abstract. There are investigated several objects of an infinite dimensional geometry, appearing from the second quantization of a free string. This paper is devoted to structures of an infinite dimensional geometry, appearing in quantum field theo...
متن کاملAlgorithms, Dehn Functions, and Automatic Groups
Ever since it was shown in the mid 1980s that being word hyperbolic was equivalent to the existence of a linear time solution to the word problem, computational and algorithmic issues have been intimately intertwined with geometric and topological ones in the study of infinite groups. The scope of this chapter is indicated by the three topics in its title: algorithms, Dehn functions, and automa...
