Lebesgue space norm inequalities are established for multilinear integral operators of Calderon-Zygmund type which incorporate oscillatory factors exp(iP), where P is a real-valued polynomial with large coefficients. A related problem concerning upper bounds for measures of sublevel sets is solved.24 pages. See also http://www.math.berkeley.edu/~mchrist/preprints.htmlClassical Analysis and ODEs42B10text
