| Outline of Final Research Achievements |
(1) We establish the existence of congruences between an endoscopic cuspidal automorphic representation of GSp(4) of level 1 and stable cuspidal automorphic representations of the same level and weight modulo certain prime factors of the value at 1 of the adjoint L-function of normalized by a suitable period.
(2) We studied the construction of Euler system associated to cuspidal representations of Gap(4). We obtained partial results on norm compatibility of certain motivic elements.
