Proc. Steklov Inst. Math. 264, 204-215 (2009); translation from Tr. Mat. Inst. Steklova 264, 212-223 (2009).
Summary: Using Galois theory, we explicitly construct absolutely simple (principally polarized) Prym varieties that are not isomorphic to jacobians of curves even if we ignore the polarizations.
