ABSTRACT

For a prime number l  and for a finite Galois l  -extension of function fields L/K  over an algebraically closed field of characteristic p /= l  , it is obtained the Galois module structure of the generalized Jacobian associated to L  , l  , and the ramified prime divisors. In the cyclic case an implicit integral representation of the Jacobian is obtained and this representation is compared with the explicit representation.
