    In this paper, we apply Tsuzuki’s main theorem in [12] to establish a criterion for when two abelian varieties over a function field of characteristic are isogenous. Specifically, assuming that their endomorphism algebras tensored with are division algebras, we prove that if the maximal quotients of minimal slope (i.e., the unique maximal isoclinic quotient corresponding to the minimal slope, defined up to isogeny) of their associated -divisible groups are isogenous, then the abelian varieties themselves are isogenous over . We also extend this result to certain -divisible groups, highlighting the deep connection between isogenies of abelian varieties and the structure of overconvergent -isocrystals.

    <p>We compare flat cohomology to crystalline syntomic complexes with coefficients in two cases: (1) -divisible groups over a separated -scheme with local finite -bases, (2) semi-abelian schemes over a separated irreducible smooth curve.</p>

    This volume collects the texts of five courses given in the Arithmetic Geometry Research Programme 2009-2010 at the CRM Barcelona. All of them deal with characteristic p global fields; the common theme around which they are centered is the arithmetic of L-functions (and other special functions), investigated in various aspects. Three courses examine some of the most important recent ideas in the positive characteristic theory discovered by Goss (a field in tumultuous development, which is seeing a number of spectacular advances): they cover respectively crystals over function fields (with a number of applications to L-functions of t-motives), gamma and zeta functions in characteristic p, and the binomial theorem. The other two are focused on topics closer to the classical theory of abelian varieties over number fields.

    We give a proof of the Iwasawa Main Conjecture for smooth Zp-sheaves (resp. semistable abelian varieties) over (resp. unramified) p-adic Lie extensions of function fields
