Abstract： I will report a joint work with H. Esnault (Stratified bundles and étale fundamental  group， Ann. Sc. Norm. Super. Pisa Cl. Sci. (5)  Vol. XIII (2014), 795-812), in which we prove the last two statements of a conjecture raised by D. Gieseker on 1975 (Ann. Scuola Norm. Sup. Pisa Cl. Sci. (2) 4 (1975), 1–31).
