    Constraints on the Value of the Fine Structure Constant From Gravitational Thermodynamics.P. C. W. Davies - unknown
    The fine structure constant α ≡ e2/ c ≈ 1/137 is one of the fundamental parameters of the standard model of particle physics. There is a long history of attempts to derive the measured value of α from an underlying theory, or exhibit it in the form of a compact mathematical expression [2–4, 6, 8, 14–16]. The most significant advance in this endeavour was made by Dirac, who showed that if magnetic monopoles exist, with magnetic charge μ, (...)

    Generic Relativizations of Fine Structure.Kai Hauser - 2000 - Archive for Mathematical Logic 39 (4):227-251.
    It is shown how certain generic extensions of a fine structural model in the sense of Mitchell and Steel [MiSt] can be reorganized as relativizations of the model to the generic object. This is then applied to the construction of Steel's core model for one Woodin cardinal [St] and its generalizations.

    Quantum Mechanics of the Supplementary Series.Andrzej Staruszkiewicz - 2002 - Foundations of Physics 32 (12):1863-1876.
    Unitary, irreducible representations of the proper, orthochronous Lorentz group comprise the main series and the supplementary series. The main series is spanned by the complete set of eigenstates of the self-adjoint Casimir operator C 1=−(1/2)M μν M μν , where M μν are generators of Lorentz transformations. The supplementary series has no such interpretation; moreover it is spurious from the point of view of functional analysis as it does not enter into the integral representation of an arbitrary test function. The (...)

    The Fine Structure of ‘Homology’.Aaron Novick - 2018 - Biology and Philosophy 33 (1-2):6.
    There is long-standing conflict between genealogical and developmental accounts of homology. This paper provides a general framework that shows that these accounts are compatible and clarifies precisely how they are related. According to this framework, understanding homology requires both an abstract genealogical account that unifies the application of the term to all types of characters used in phylogenetic systematics and locally enriched accounts that apply only to specific types of characters. The genealogical account serves this unifying role by relying on (...)

    The Fine Structure of Real Mice.Daniel W. Cunningham - 1998 - Journal of Symbolic Logic 63 (3):937-994.
    Before one can construct scales of minimal complexity in the Real Core Model, K(R), one needs to develop the fine-structure theory of K(R). In this paper, the fine structure theory of mice, first introduced by Dodd and Jensen, is generalized to that of real mice. A relative criterion for mouse iterability is presented together with two theorems concerning the definability of this criterion. The proof of the first theorem requires only fine structure; whereas, the (...)

    The Fine Structure of the Intuitionistic Borel Hierarchy.Wim Veldman - 2009 - Review of Symbolic Logic 2 (1):30-101.
    In intuitionistic analysis, a subset of a Polish space like or is called positively Borel if and only if it is an open subset of the space or a closed subset of the space or the result of forming either the countable union or the countable intersection of an infinite sequence of (earlier constructed) positively Borel subsets of the space. The operation of taking the complement is absent from this inductive definition, and, in fact, the complement of a positively Borel (...)

    Cholak, Goncharov, Khoussainov, and Shore [1] showed that for each k > 0 there is a computably categorical structure whose expansion by a constant has computable dimension k. We show that the same is true with k replaced by ω. Our proof uses a version of Goncharov's method of left and right operations.

  14. A Constant of Temporal Structure in the Human Hierarchy and Other Systems.Peter W. Barlow - 1992 - Acta Biotheoretica 40 (4):321-328.
    The levels that compose biological hierarchies each have their own energetic, spatial and temporal structure. Indeed, it is the discontinuity in energy relationships between levels, as well as the similarity of sub-systems that support them, that permits levels to be defined. In this paper, the temporal structure of living hierarchies, in particular that pertaining to Human society, is examined. Consideration is given to the period defining the lifespan of entities at each level and to a periodic event considered (...)

  15. The Grammar of Quantification and the Fine Structure of Interpretation Contexts.Adrian Brasoveanu - 2013 - Synthese 190 (15):3001-3051.
    Providing a compositional interpretation procedure for discourses in which descriptions of complex dependencies between interrelated objects are incrementally built is a key challenge for formal theories of natural language interpretation. This paper examines several quantificational phenomena and argues that to account for these phenomena, we need richly structured contexts of interpretation that are passed on between different parts of the same sentence and also across sentential boundaries. The main contribution of the paper is showing how we can add structure (...)

    On the Fine Structure of the Polygroup Blow-Up.Itay Ben-Yaacov - 2003 - Archive for Mathematical Logic 42 (7):649-663.
    We study in detail the blow-up procedure described in [BTW01]. We obtain a structure theorem for coreless polygroups as a double quotient space G//H, and a polygroup chunk theorem. Seeking to remove the arbitrary parameter needed for the blow-up, we find canonical Ø-invariant groupoids.

    Accounting for the Fine Structure of Syntactic Working Memory: Similarity-Based Interference as a Unifying Principle.Richard L. Lewis - 1999 - Behavioral and Brain Sciences 22 (1):105-106.
    A promising approach to more refined models consistent with the Caplan & Waters hypothesis is based on similarity-based interference, a general principle that applies across working memory domains. This may explain both the fine details of syntactic working memory phenomena and the gross fractionation for which Caplan & Waters have found evidence. Detailed models of syntactic processing that embody similarity-based interference fare well cross-linguistically.

    The Fine Structure of Inference to the Best Explanation. [REVIEW]Stathis Psillos - 2007 - Philosophy and Phenomenological Research 74 (2):441–448.
    Traditionally, philosophers have focused mostly on the logical template of inference. The paradigm-case has been deductive inference, which is topic-neutral and context-insensitive. The study of deductive rules has engendered the search for the Holy Grail: syntactic and topic-neutral accounts of all prima facie reasonable inferential rules. The search has hoped to find rules that are transparent and algorithmic, and whose following will just be a matter of grasping their logical form. Part of the search for the Holy Grail has been (...)

    The Fine Structure of Peircean Ligatures and Lines of Identity.Robert W. Burch - 2011 - Semiotica 2011 (186):21-68.
    Lines of identity in Peirce's existential graphs are logically complex structures that comprise both identity and existential quantification. Yet geometrically they are simple: linear continua that cannot have “furcations” or cross “cuts.” By contrast Peirce's “ligatures” are geometrically complex: they can both have furcations and cross cuts. Logically they involve not only identity and existential quantification but also negation. Moreover, Peirce makes clear that ligatures are composed of lines of identity by virtue of the fact that such lines can be (...)

    In this paper we introduce a collection of isols having some interesting properties. Imagine a collection W of regressive isols with the following features: u, v ϵ W implies that u ⩽ v or v ⩽ u, u ⩽ v and v ϵ W imply u ϵ W, W contains ℕ = {0,1,2,…} and some infinite isols, and u eϵ W, u infinite, and u + v regressive imply u + v ϵ W. That such a collection W exists is (...)
