我们提出了一个实手性费米场的代数与 n 个实手性费米场的代数之间的简单同构。同构保持了真空状态。这可以通过“局域改变”来实现,并产生由相应的多局域电流和应力-能量张量生成的新的多局域对称性。该结果对最近关于用自由费米场表示自由玻色场的几个显着结果提供了共同的基本解释(Anguelova,arXiv:1112.3913,2011;Anguelova,arXiv:1206.4026,2012),以及关于不相交区间中的自由费米代数的模理论(Casini和Huerta,Class Quant Grav) 26:185005, 2009;Longo 等人,Rev Math Phys 22:331–354, 2010)数学学科分类。 81T40。
We present a simple isomorphism between the algebra of one real chiral Fermi field and the algebra of n real chiral Fermi fields. The isomorphism preserves the vacuum state. This is possible by a “change of localization”, and gives rise to new multilocal symmetries generated by the corresponding multilocal current and stress–energy tensor. The result gives a common underlying explanation of several remarkable recent results on the representation of the free Bose field in terms of free Fermi fields (Anguelova, arXiv:1112.3913, 2011; Anguelova, arXiv:1206.4026, 2012), and on the modular theory of the free Fermi algebra in disjoint intervals (Casini and Huerta, Class Quant Grav 26:185005, 2009; Longo et al., Rev Math Phys 22:331–354, 2010) Mathematics Subject Classification. 81T40.
