An Algorithm for Decomposing Polynomial System into Normal Ascending Sets
We present an algorithm to decompose a polynomial system into a finite set of normal ascending sets such that the set of the zeros of the polynomial system is the union of the sets of the regular zeros of the normal ascending sets. If the polynomial system is 0-dimensional, the set of the zeros of the polynomials is the union of the sets of the zeros of the normal ascending sets.
متن کاملDecomposing the real line into Borel sets closed under addition
We consider decompositions of the real line into pairwise disjoint Borel pieces so that each piece is closed under addition. How many pieces can there be? We prove among others that the number of pieces is either at most 3 or uncountable, and we show that it is undecidable in ZFC and even in the theory ZFC + c = ω2 if the number of pieces can be uncountable but less than the continuum. We also ...
متن کاملDecomposing Sets of Inversions
In this paper we consider the question how the set of inversions of a permutation π ∈ Sn can be partitioned into two subsets, which are themselves inversion sets of permutations in Sn. Our method is to study the modular decomposition of the inversion graph of π. A correspondence to the substitution decomposition of π is also given. Moreover, we consider the special case of multiplicative decomp...
متن کاملSkewness modes in the Northern Hemisphere winter
The probability distribution of daily Northern Hemisphere streamfunction fluctuations at 500 hPa in winter is skewed at most locations. Large positive anomalies are more likely north of 50N with maximum values of the skewness in the North Pacific and North Atlantic region. In this study we develop two novel methodologies in order to diagnose the underlying circulation structures associated with...
متن کاملDecomposing Matrices into Blocks
In this paper we investigate whether matrices arising from linear or integer programming problems can be decomposed into so-called bordered block diagonal form. More precisely, given some matrix A, we try to assign as many rows as possible to some number β of blocks of size κ such that no two rows assigned to different blocks intersect in a common column. Bordered block diagonal form is desirab...
