    pointed convergence..

    i dont know if its the correct term.

    http://i34.tinypic.com/2eozlns.jpg

    pointed convergence says that it convergence on a certain point.

    i know from calculus some tests that say if a series converges or not

    but here its so different

    "Pointwise convegence" would be the standard English term.
