复超曲面的约束估计

Restriction estimates to complex hypersurfaces

Juyoung Lee, Sanghyuk Lee

摘要:

超曲面的约束问题得到了更好的理解,最近的进展已经取得了双线性和多线性的方法,最近的多项式分割方法,结合这些估计。然而,对于余维数大于1的曲面,双线性和多线性推广的限制估计涉及更多,这些多线性估计的有效性还没有得到很好的理解。关于余维大于1的曲面的限制问题,目前的技术水平仍然是$TT^*$方法,已知该方法可用于获得$L^q$ - $L^2$限制估计。本文考虑了一类特殊的余维2曲面,它由复解析函数的图给出,并试图在$L^2$限制估计的基础上有所进展。

英文摘要:

The restriction problem is better understood for hypersurfaces and recent progresses have been made by bilinear and multilinear approaches and most recently polynomial partitioning method which is combined with those estimates. However, for surfaces with codimension bigger than 1, bilinear and multilinear generalization of restriction estimates are more involved and effectiveness of these multilinear estimates is not so well understood yet. Regarding the restriction problem for the surfaces with codimensions bigger than 1, the current state of the art is still at the level of $TT^*$ method which is known to be useful for obtaining $L^q$--$L^2$ restriction estimates. In this paper, we consider a special type of codimension 2 surfaces which are given by graphs of complex analytic functions and attempt to make progress beyond the $L^2$ restriction estimates.
