Abstract:  Euler systems are compatible families of cohomology classes for a global Galois represenation, which plan an important role in studying Selmer groups.  I will outline the construction of a new Euler system, for the Galois representation associated to a cohomological cuspidal automorphic representation on the symplectic group GSp(4).  This is joint work with Chris Skinner and Sarah Zerbes.
