利用三角分解计算柱形代数分解

Computing Cylindrical Algebraic Decomposition via Triangular Decomposition

Changbo Chen, Marc Moreno Maza, Bican Xia, Lu Yang

摘要:

柱形代数分解是处理半代数集合的重要工具之一,而三角分解是处理可构造集合的重要方法之一。本文对任意有限集$F \subset {\R}[y_1, ..., y_n]$,应用综合三角分解,得到了$n$维复空间的$F$ -不变圆柱分解,并由此得到了$n$维实空间的$F$ -不变柱形代数分解.我们报告的实施这种新的方法来构建柱形代数分解。

英文摘要:

Cylindrical algebraic decomposition is one of the most important tools for computing with semi-algebraic sets, while triangular decomposition is among the most important approaches for manipulating constructible sets. In this paper, for an arbitrary finite set $F \subset {\R}[y_1, ..., y_n]$ we apply comprehensive triangular decomposition in order to obtain an $F$-invariant cylindrical decomposition of the $n$-dimensional complex space, from which we extract an $F$-invariant cylindrical algebraic decomposition of the $n$-dimensional real space. We report on an implementation of this new approach for constructing cylindrical algebraic decompositions.
