Amalgamation functors and homology groups in model theory, part I. In this joint work of John Goodrick, Byunghan Kim, and Alexei Kolesnikov, we develop basics of homology theory in a model-theoretic context and connect it with generalized amalgamation properties. This talk will introduce definitions of homology groups Hn, n ≥ 0, associated to a family of “amalgamation functors”. Main resutls are: If the generalized amalgamation properties hold, then the homology groups are trivial; H2 for strong types in stable theories are profinite abelian.

Amalgamation functors and homology groups in model theory, part II. This talk will continue the exposition of the work by John Goodrick, Byunghan Kim, and Alexei Kolesnikov. We will present examples illustrating the main notions, outline the proof of the “Prism Lemma” (an important technical result used in the calculation of the homology groups). Finally, we will compute the group H2 for strong types in stable theories and show that any profinite abelian group can occur as the group H2 in the model-theoretic context.

  • Extreme and Exposed Representing Measures of the Disk Algebra
    ANNALES POLONICI MATHEMATICI LXXIII.2 (2000) Extreme and exposed representing measures of the disk algebra by Alex Heinis (Leiden) and Jan Wiegerinck (Amsterdam) Abstract. We study the extreme and exposed points of the convex set consisting of representing measures of the disk algebra, supported in the closed unit disk. A boundary point of this set is shown to be extreme (and even exposed) if its support inside the open unit disk consists of two points that do not lie on the same radius of the disk. If its support inside the unit disk consists of 3 or more points, it is very seldom an extreme point. We also give a necessary condition for extreme points to be exposed and show that so-called BSZ-measures are never exposed. 1. Introduction and notational matters. In a previous paper [2] Brummelhuis and the second author studied representing measures for the disk algebra A = A(D)= {f ∈ C(D) | f is holomorphic on D}, where D is the unit disk in C. As usual A is endowed with the structure of a uniform algebra. Its spectrum equals D. That is, every homomorphism φ : A → C is of the form f 7→ f(x) for some x ∈ D. The Hahn–Banach theorem allows for a multitude of extensions of φ as a continuous linear functional on C(D). The dual space C(D)∗ can be identified with M, the space of complex Borel measures on D endowed with the weak∗ topology by the Riesz representation theorem. A representing measure µ for x ∈ D is a positive Borel measure on D such that \ f dµ = f(x) ∀f ∈ A.

    A PRIMER ON SUBSTITUTION TILINGS OF THE EUCLIDEAN PLANE NATALIE PRIEBE FRANK Abstract. This paper is intended to provide an introduction to the theory of substitution tilings. For our purposes, tiling substitution rules are divided into two broad classes: geometric and combi- natorial. Geometric substitution tilings include self-similar tilings such as the well-known Penrose tilings; for this class there is a substantial body of research in the literature. Combinatorial sub- stitutions are just beginning to be examined, and some of what we present here is new. We give numerous examples, mention selected major results, discuss connections between the two classes of substitutions, include current research perspectives and questions, and provide an extensive bib- liography. Although the author attempts to fairly represent the as a whole, the paper is not an exhaustive survey, and she apologizes for any important omissions. 1. Introduction d A tiling substitution rule is a rule that can be used to construct infinite tilings of R using a finite number of tile types. The rule tells us how to \substitute" each tile type by a finite configuration of tiles in a way that can be repeated, growing ever larger pieces of tiling at each stage. In the d limit, an infinite tiling of R is obtained. In this paper we take the perspective that there are two major classes of tiling substitution rules: those based on a linear expansion map and those relying instead upon a sort of \concatenation" of tiles. The first class, which we call geometric tiling substitutions, includes self-similar tilings, of which there are several well-known examples including the Penrose tilings.

  • Combinatorial Design University of Southern California Non-Parametric Computational Design Strategies
    Jose Sanchez Combinatorial design University of Southern California Non-parametric computational design strategies 1 ABSTRACT This paper outlines a framework and conceptualization of combinatorial design. Combinatorial 1 Design – Year 3 – Pattern of one design is a term coined to describe non-parametric design strategies that focus on the permutation, unit in two scales. Developed by combinatorial design within a game combination and patterning of discrete units. These design strategies differ substantially from para- engine. metric design strategies as they do not operate under continuous numerical evaluations, intervals or ratios but rather finite discrete sets. The conceptualization of this term and the differences with other design strategies are portrayed by the work done in the last 3 years of research at University of Southern California under the Polyomino agenda. The work, conducted together with students, has studied the use of discrete sets and combinatorial strategies within virtual reality environments to allow for an enhanced decision making process, one in which human intuition is coupled to algo- rithmic intelligence. The work of the research unit has been sponsored and tested by the company Stratays for ongoing research on crowd-sourced design. 44 INTRODUCTION—OUTSIDE THE PARAMETRIC UMBRELLA To start, it is important that we understand that the use of the terms parametric and combinatorial that will be used in this paper will come from an architectural and design background, as the association of these terms in mathematics and statistics might have a different connotation. There are certainly lessons and a direct relation between the term ‘combinatorial’ as used in this paper and the field of combinatorics and permutations in mathematics.

    The Book Review Column1 by William Gasarch Department of Computer Science University of Maryland at College Park College Park, MD, 20742 email: [email protected] In this column we review the following books. 1. Combinatorial Designs: Constructions and Analysis by Douglas R. Stinson. Review by Gregory Taylor. A combinatorial design is a set of sets of (say) {1, . , n} that have various properties, such as that no two of them have a large intersection. For what parameters do such designs exist? This is an interesting question that touches on many branches of math for both origin and application. 2. Combinatorics of Permutations by Mikl´osB´ona. Review by Gregory Taylor. Usually permutations are viewed as a tool in combinatorics. In this book they are considered as objects worthy of study in and of themselves. 3. Enumerative Combinatorics by Charalambos A. Charalambides. Review by Sergey Ki- taev, 2008. Enumerative combinatorics is a branch of combinatorics concerned with counting objects satisfying certain criteria. This is a far reaching and deep question. 4. Geometric Algebra for Computer Science by L. Dorst, D. Fontijne, and S. Mann. Review by B. Fasy and D. Millman. How can we view Geometry in terms that a computer can understand and deal with? This book helps answer that question. 5.

  • The Language of Differential Forms
    Appendix A The Language of Differential Forms This appendix—with the only exception of Sect.A.4.2—does not contain any new physical notions with respect to the previous chapters, but has the purpose of deriving and rewriting some of the previous results using a different language: the language of the so-called differential (or exterior) forms. Thanks to this language we can rewrite all equations in a more compact form, where all tensor indices referred to the diffeomorphisms of the curved space–time are “hidden” inside the variables, with great formal simplifications and benefits (especially in the context of the variational computations). The matter of this appendix is not intended to provide a complete nor a rigorous introduction to this formalism: it should be regarded only as a first, intuitive and oper- ational approach to the calculus of differential forms (also called exterior calculus, or “Cartan calculus”). The main purpose is to quickly put the reader in the position of understanding, and also independently performing, various computations typical of a geometric model of gravity. The readers interested in a more rigorous discussion of differential forms are referred, for instance, to the book [22] of the bibliography. Let us finally notice that in this appendix we will follow the conventions introduced in Chap. 12, Sect. 12.1: latin letters a, b, c,...will denote Lorentz indices in the flat tangent space, Greek letters μ, ν, α,... tensor indices in the curved manifold. For the matter fields we will always use natural units = c = 1. Also, unless otherwise stated, in the first three Sects.

  • Minimally Separating Sets, Mediatrices, and Brillouin Spaces
    MINIMALLY SEPARATING SETS, MEDIATRICES, AND BRILLOUIN SPACES J.J.P. VEERMAN AND JAMES BERNHARD Abstract. Brillouin zones and their boundaries were studied in [16] because they play an important role in focal decomposition as first defined by Peixoto in [9] and in physics ([1] and [3]). In so-called Brillouin spaces, the boundaries of the Brillouin zones have certain regularity properties which imply that they consist of pieces of mediatrices (or equidistant sets). The purpose of this note is two-fold. First, we give some simple conditions on a metric space which are sufficient for it to be a Brillouin space. These con- ditions show, for example, that all compact, connected Riemannian manifolds with their usual distance functions are Brillouin spaces. Second, we exhibit a restriction on the Z2-homology of mediatrices in such manifolds in terms of the Z2-homology of the manifolds themselves, based on the fact that they are Bril- louin spaces. (This will used to obtain a classification up to homeomorphim of surface mediatrices in [15]). This note begins with some preliminaries in Section 1, where we define the relevant concepts and provide some background and motivation for the questions being considered here. In Section 2, we list a simple set of conditions on a metric space and prove that these conditions suffice for it to be a Brillouin space. In Section 3, we give some examples and mention a result for use in a later paper. We then investigate in Section 4 the homological restrictions placed on a mediatrix by the topology of the surrounding Brillouin space.
