Informative Models: Idealization and Abstraction
2021Mauricio Suárez and Agnes Bolinska apply the tools of communication theory to scientific modeling in order to characterize the informational content of a scientific model. They argue that when represented as a communication channel, a model source conveys information about its target, and that such representations are therefore appropriate whenever ...

THE ANNIHILATING IDEALS OF MINIMAL MODELS
International Journal of Modern Physics A, 1992We describe several aspects of the annihilating ideals and reduced chiral algebras of conformal field theories, especially, minimal models of Wn algebras. The structure of the annihilating ideal and a vanishing condition is given. Using the annihilating ideal, the structure of quasi-finite models of the Virasoro (2,q) minimal models are studied, and ...

Abstract In chapter one I introduce the concepts of idealization and modeling, discuss their relation, and provide some examples of model-building in philosophy. I show that idealization, at least in the broad sense in which I use the term, is ubiquitous in epistemology.

The self ideal versus the model ideal
Journal of Religion and Health, 1982A list of 50 ways of perceiving one's personal ideal was constructed and administered to 74 women about to make a lifelong commitment. The mean number of items endorsed was 28. An item analysis yielded discrimination indices for 28 items at better than the .05 level of significance.

A MODEL WITH A PRECIPITOUS IDEAL, BUT NO NORMAL PRECIPITOUS IDEAL
Journal of Mathematical Logic, 2013Starting with a measurable cardinal κ of the Mitchell order κ++ we construct a model with a precipitous ideal on ℵ1 but without normal precipitous ideals. This answers a question by T. Jech and K. Prikry. In the constructed model there are no Q-point precipitous filters on ℵ1, i. e. those isomorphic to extensions of Cubℵ1.

Models of arithmetic and closed ideals
Journal of Symbolic Logic, 1982A set J of Turing degrees is called an ideal if (1) J ≠ ∅, (2) for any pair of degrees ã, , if ã, ϵ J, then ã ⋃ ϵJ, and (3) for any ⋃ ϵ J and any , if < ⋃, then ϵ J. A set J of degrees is said to be closed if for any theory T with a set of axioms of degree in J, T has a completion of degree in J.Closed ideals of degrees arise naturally in the ...

A Formal Model for an Ideal CFI
2017We provide a formal model to achieve a fully precise dynamic protection of the flow of execution against control flow hijacking attacks. In more than a decade since the original Control Flow Integrity the focus of all of the proposed work in the literature has been on practical implementation of CFI. This however due to the restriction that the classic

Idealization and abstraction in scientific modeling
Synthese, 2018I argue that we cannot adequately characterize idealization and abstraction and the distinction between the two on the grounds that they have distinct semantic properties. By doing so, on the one hand, we focus on the conceptual products of the two processes in making the distinction and we overlook the importance of the nature of the thought processes

Ideal models and some not so ideal problems in the model theory of L(Q)
Journal of Symbolic Logic, 1978It is the purpose of this paper to investigate the model theory of logic with a generalized quantifier; in particular the logic L(Q1) where Q1xφ(x) has the intended meaning “there exist uncountably many x such that φ(x)”. We do this from the point of view that the best way to study what happens in the so-called “ω1-standard” models of L(Q1) is to ...
