\n\tAbstract: \n<\/p>\n
\n\tWe prove that the monodromy of a cohomologically rigid integrable connection on a smooth complex projective variety is integral. This answers positively a special case of a conjecture by Carlos Simpson. To this aim, we use $F$-isocrystals and $\\ell$-adic companions. Joint with Michael Groechenig.\n<\/p>\n
