%0 Journal Article %T Picard numbers of complex Delsarte surfaces with only isolated ADE-singularities %A Bas Heijne %J Mathematics %D 2012 %I arXiv %X We give a classification of all Delsarte surfaces with only ADE singularities. Using this we give closed formulas for the Picard numbers of such surfaces. %U http://arxiv.org/abs/1212.5006v4
