Canonical quantization of 1+ 1-dimensional Yang-Mills theory: an operator-algebraic approach

A Brothier, A Stottmeister - arxiv preprint arxiv:1907.05549, 2019 - arxiv.org
We present a mathematically rigorous canonical quantization of Yang-Mills theory in 1+ 1
dimensions (YM $ _ {1+ 1} $) by operator-algebraic methods. The latter are based on …

Uniqueness of the Fock quantization of fields with unitary dynamics in nonstationary spacetimes

J Cortez, GA Mena Marugan, J Olmedo… - Physical Review D …, 2011 - APS
The Fock quantization of fields propagating in cosmological spacetimes is not uniquely
determined because of several reasons. Apart from the ambiguity in the choice of the …
