Abstract:
In the paper, the concrete generators are found for the annihilating ideal of the modular symbols associated with $SL(s;\mathbb{Z})$. Using this result, the (co)homology of subgroups of finite index is evaluated for $SL(s;\mathbb{Z})$.
Keywords:modular form, modular element, modular symbol, Eichler–Shimura module, annihilator ideal, generators of an ideal.
