Group Envy Freeness and Group Pareto Efficiency in Fair Division with Indivisible Items
Deutsche Jahrestagung für Künstliche Intelligenz, 2018We study the fair division of items to agents supposing that agents can form groups. We thus give natural generalizations of popular concepts such as envy-freeness and Pareto efficiency to groups of fixed sizes. Group envy-freeness requires that no group

Scale Freeness in Factor Analysis
Psychometrika, 1978The notion of scale freeness does not seem to have been well understood in the factor analytic literature. It has been believed that if the loss function that is minimized to obtain estimates of the parameters in the factor model is scale invariant, then the estimates are scale free.

Normally torsion-freeness of monomial ideals under monomial operators
Communications in Algebra, 2018An ideal I in a commutative Noetherian ring R is called normally torsion-free if for all positive integers k. In this article, by using some monomial operators, such as expansion, weighted, monomial multiple, monomial localization, contraction, and ...

q-Torsion freeness of symmetric powers
Rendiconti del Circolo Matematico di Palermo, 1997Let \(R\) be a commutative noetherian unitary ring and \(E\) a finitely generated \(R\)-module. Let \(S_R(E)\) be the symmetric algebra of \(E\) over \(R\) and \(S_R(R^n)= R[X_1,\dots, X_n]\) the polynomial ring over \(R\). If \(E\) is of rank \(e\) and of finite projective dimension then there is an epimorphism between the cycles of the Koszul complex

A homological characterization for freeness of multi-arrangements
Mathematische Annalen, 2018Building on work of Brandt and Terao in their study of k -formality, we introduce a co-chain complex associated to a multi-arrangement and prove that its cohomologies determine freeness of the associated module of multi-derivations.

On Testing Minor-Freeness in Bounded Degree Graphs With One-Sided Error
International Colloquium on Automata, Languages and Programming, 2017We consider one-sided error property testing of F-minor freeness in bounded-degree graphs for any finite family of graphs F that contains a minor of K_{2,k}, the k-circus graph, or the (k x 2)-grid for any k in N.

Freeness Analysis Through Linear Refinement
1999Linear refinement is a technique for systematically constructing abstract domains for program analysis directly from a basic domain representing just the property of interest. This paper for the first time uses linear refinement to construct a new domain instead of just reconstructing an existing one.

Local Freeness of Profinite Groups
Canadian Mathematical Bulletin, 1982AbstractIn this paper we discuss the relationship between local properties such as freeness and projectivity of a group and the freeness or projectivity of its pro-C-completion. We show that for certain classes, C, of finite groups (e.g. p-groups, nilpotent groups, super-solvable groups) the pro-C-completion of a locally free pro-C-group is a free pro ...

Scale-Freeness and Biological Networks
The Journal of Biochemistry, 2005The notion of scale-freeness and its prevalence in both natural and artificial networks have recently attracted much attention. The concept of scale-freeness is enthusiastically applied to almost any conceivable network, usually with affirmative conclusions.
