Journal of Mathematical Sciences, 279(6), 730–737. https://doi.org/10.1007/s10958-024-07055-7https://doi.org/10.1007/s10958-024-07055-7https://doi.org/10.1007/s10958-024-07055-7We extend gap functions to quasi-equilibrium problems by using the duality results. In particular, we obtain new results for quasi-equilibrium problems known earlier for equilibrium problems and mixed quasi-variational inequalities. Bibliography: 12 titles.enArticle
