Inspired by direct and indirect maximal center gauge methods which identify vortices in lattice calculations, and by using the connection formalism, we show that under some appropriate gauge transformations, vortices and chains appear in the continuum limit of QCD vacuum.Comment: 5 page, Contribution to: 19th International Conference on Hadron Spectroscopy and Structure in memoriam Simon Eidelman (HADRON 2021
