As an application, it is shown that the commutativity requirement of missing label operators for reduction chains in the missing label problem can be solved analyticallyengjournal articlehttps//doi.org/10.1088/1751-8113/42/23/235203http://iopscience.iop.org/1751-8121/42/23/235203/open access514.154Teoría de los quanta2210.23 Teoría Cuántica
