We study the generalized hypergeometric function m+1βFmβ and the
differential equation m+1βEmβ satisfied by it. We use the twisted
(co)homology groups associated with an integral representation of Euler type.
We evaluate the intersection numbers of some twisted cocycles which are defined
as m-th exterior products of logarithmic 1-forms. We also give twisted
cycles corresponding to the series solutions to m+1βEmβ, and evaluate the
intersection numbers of them. These intersection numbers of the twisted
(co)cycles lead twisted period relations which give relations for two
fundamental systems of solutions to m+1βEmβ.Comment: 13 page
