Dalian University of Technology(大连理工大学)

Zhaoliang Meng, Zhongxuan Luo

AI总结:

针对对称测度的n维立方体和n维球对称区域,构造了最多含n^2+5n+3个点和n^2+3n+3个点的5次求积公式,并在n=7时分别可减少至n^2+3n+1和n^2+n+1个点,后者达到最小。

摘要:

本文将致力于构造一族针对具有对称测度的$n$维立方体和$n$维球对称区域的五次求积公式。对于$n$维立方体,该公式最多包含$n^2+5n+3$个点;对于$n$维球对称区域,仅包含$n^2+3n+3$个点。此外,当$n=7$时,点数可分别减少至$n^2+3n+1$和$n^2+n+1$,后者是最小值。

英文摘要:

This paper will devote to construct a family of fifth degree cubature formulae for $n$-cube with symmetric measure and $n$-dimensional spherically symmetrical region. The formula for $n$-cube contains at most $n^2+5n+3$ points and for $n$-dimensional spherically symmetrical region contains only $n^2+3n+3$ points. Moreover, the numbers can be reduced to $n^2+3n+1$ and $n^2+n+1$ if $n=7$ respectively, the later of which is minimal.
