Comparing Powers and Symbolic Powers of Ideals
We develop tools to study the problem of containment of symbolic powers I(m) in powers I for a homogeneous ideal I in a polynomial ring k[P ] in N + 1 variables over an arbitrary algebraically closed field k. We obtain results on the structure of the set of pairs (r, m) such that I(m) ⊆ I. As corollaries, we show that I2 contains I(3) whenever S is a finite generic set of points in P2 (thereby ...
متن کاملPowers of Two Modulo Powers of Three
Since 2 is a primitive root of 3 for each positive integer m, the set of points {(n, 2 mod 3) : n > 0}, viewed as a subset of Z>0×Z>0 is bi-periodic, with minimal periods φ(3) (horizontally) and 3 (vertically). We show that if one considers the classes of n modulo 6, one obtains a finer structural classification. This result is presented within the context of the question of strong normality of...
متن کاملDomination number of graph fractional powers
For any $k in mathbb{N}$, the $k$-subdivision of graph $G$ is a simple graph $G^{frac{1}{k}}$, which is constructed by replacing each edge of $G$ with a path of length $k$. In [Moharram N. Iradmusa, On colorings of graph fractional powers, Discrete Math., (310) 2010, No. 10-11, 1551-1556] the $m$th power of the $n$-subdivision of $G$ has been introduced as a fractional power of $G$, denoted by ...
متن کاملGovernment’s Powers and FTAs: The Effect of Domestic and Foreign Powers on Multilateral Trade
This paper elaborates on the government's powers - both at the domestic level and over foreign countries. The domestic power is the power against domestic lobbies, and the foreign one is the government's international power. To do so, this paper tries to evaluate the effects of these powers on the formation of free trade agreements (FTAs). The theoretical framework follows an oligopolistic-po...
متن کاملAristotelian Powers
Aristotle's theory of causation has multiple threads, and his texts invite multiple interpretations. The variation in interpretation is, in part, a result of different perspectives and questions that are brought to the text. For instance, Aristotle's theory of the four causes has invited scrutiny from contemporary philosophers of science, who are interested in theories of explanation (van Fraas...
