Freeness in classes without equality
Journal of Symbolic Logic, 1999AbstractThis paper is a continuation of [27], where we provide the background and the basic tools for studying the structural properties of classes of models over languages without equality. In the context of such languages, it is natural to make distinction between two kinds of classes, the so-calledabstruct classes, which correspond to those closed ...

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.

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.

Expressive Capacity of Concatenation Freeness
2015The expressive capacity of regular expressions without concatenation, but with complementation and a finite set of words as literals is studied. In particular, a characterization of unary concatenation-free languages by the Boolean closure of certain sets of languages is shown.

Similarity Relations and Repetition-Freeness
2013A similarity relation is a relation on words of equal length induced by a symmetric and reflexive relation on letters. The aim of this article is to give an overview of the results concerning repetition-freeness in connection with similarity relations.
