Can we compute denominators of Eisenstein classes?
G. Harder
We discuss the general conjecture that the denominators of Eisenstein classes should be related
to the prime factorisation of certain special values of Lfunctions.
We propose an experimental procedure to verify (or falsify) this conjecture in a given special case.
We also discuss an interesting special case, where this experimental approach could be tested.
