非对易Moyal空间上的紫外-红外混合问题

The ultraviolet infrared mixing problem on the noncommutative Moyal space

Dorothea Bahns

摘要:

结果表明,Moyal空间上的量子场论中的紫外和红外发散的混合不是欧几里德框架的假象,而是在相互作用用Moyal扭曲卷积积表示的哈密顿体系中也会发生.在这两种设置的混合机制进行检查,从微观局部分析的角度来看,它表明,它们是彼此不同的。

英文摘要:

It is shown that the mixing of ultraviolet and infrared divergences in quantum field theory on Moyal space is not an artefact of the Euclidean framework, but occurs also in the Hamiltonian setting when the interaction is given in terms of the Moyal twisted convolution product. The mixing mechanism in both settings is examined from the point of view of microlocal analysis and it is shown that they are different from one another.
