It is unknown whether the Flint Hills series. ∑n=1∞ 1 n3sin2 n. converges or not. The difficulty here is that convergence depends on the term n sin n not being too small, which in turn depends on how well π can be approximated by rational numbers. It is possible that, if π can be approximated `too well' by rationals, then this will diverge.please do contact me.

Many real unsolved math problems appear similarly abstract. One example is the Hodge conjecture, a Millennium Prize problem. It states "Let X be a non-singular complex projective manifold. Then every Hodge class on X is a linear combination with rational coefficients of the cohomology classes of complex subvarieties of X."
