Unitary groupFermionic operatorsThe non-standard Schwinger fermionic representation of the unitary group is studied by using n -fermion operators. One finds that the Schwinger fermionic representation of the U ( n ) group is not unique when n ≥3. In general, based on n -fermion operators, ...
读过 Representation Theory of Semisimple Groups Plancherel formula 1 以Chapter 10 介绍的Distribution character 为基础,第11章介绍了SU(2), SL(2,C), SL(2,R) 上的Plancherel formula,证明了出现在对应的 L^2(G)空间中的unitary representations 应该是什么样的形式。实际上,第10章至13章,都是围绕这个...

Representation theory represents elements of groups as linear transformations of vector spaces, as these latter structures are much easier to understand and work with. Let G be a group with a unit element e, and let ℋ be a Hilbert space. A unitary representation of G is a function U: G...
Knapp offers a survey of representation theory of semisimple Lie groups in a way that reflects the spirit of the subject and corresponds to the natural learning process. This book is a model of exposition and an invaluable resource for both graduate students and researchers. Although theorems are...
In standard quantum field theory, the one-particle states are classified bythe unitary representations of the Poincar\\'e group, whereas the causal fields'... M Kaźmierczak - 《Radioprotection》 被引量: 1发表: 2009年 Constructing Mathematical Concepts through External Representations Utilizing Techno...
The actual construction is based on the observation that one can fix a family TA of unitary operators in the Hilbert H of square integrable spinor fields on S3 as a function of the external vector potential A such that the operators TAg−1gTA satisfy the condition in [4] to be ...
