The internal global symmetries act just as locally on the lattice as they do in the continuum, the anomalies are reproduced at finite lattice spacing, and in each case we find a sign-problem-free dual formulation.}, cin = {IAS-4 / CASA / JSC / IKP-3}, cid = {I:(DE-Juel1)IAS-4-20090406 / I:(DE-Juel1)CASA-20230315 / I:(DE-Juel1)JSC-20090406 / I:(DE-Juel1)VDB25}, pnm = {5111 - Domain-Specific Simulation $\&$ Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)}, pid = {G:(DE-HGF)POF4-5111}, typ = {PUB:(DE-HGF)25}, eprint = {2310.17539}, howpublished = {arXiv:2310.17539}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2310.17539;\%\%$}, doi = {10.34734/FZJ-2023-05410}, url = {https://juser.fz-juelich.de/record/1019463}, }
