  1. 1. Enthymemes in Dialogue: A micro-rhetorical approach

    Author : Ellen Breitholtz; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; Topos; Enthymeme; ; TTR; Dialogue modelling; Non-monotonic reasoning; Accommodation; Micro-rhetoric; Gameboard semantics;

    Abstract : In dialogue we frequently present arguments which are based on commonly accepted non-logical inferences. In rhetorical theory, this type of argument is called an enthymeme, and a pattern of reasoning that it is based on is called a topos. The main purpose of this thesis is to investigate the role that enthymemes play in natural language dialogue. READ MORE

  2. 2. Metal Organic Frameworks: History, Synthesis, and Topological approach

    Author : Cédric Borel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MOF; crystal structures; crystal engineering; network; coordination chemistry; synthesis; TOPOS; systre; gas storage;

    Abstract : The storage, separation, purification and catalytic reactions of small molecules are important research domains in both pure and applied chemistry, where porous materials play a major role. Among the different possible options for the preparation porous materials a recent approach is to build structures based on metal ions, metal complexes, or metal clusters, bridged by organic ligands.

  3. 3. Localic Categories of Models and Categorical Aspects of Intuitionistic Ramified Type Theory

    Author : Johan Lindberg; Erik Palmgren; Peter LeFanu Lumsdaine; Henrik Forssell; Benno van den Berg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topos theory; predicative topos theory; ramified type theory; type theory; localic groupoids; Mathematics; matematik;

    Abstract : This thesis contains three papers, all in the general area of categorical logic, together with an introductory part with some minor results and proofs of known results which does not appear to be (easily) available in the literature.In Papers I and II we investigate the formal system Intuitionistic Ramified Type Theory (IRTT), introduced by Erik Palmgren, as an approach to predicative topos theory.

  4. 4. Constructive Newton–Puiseux Theorem, Sheaf Model of the Separable Closure and Dynamic Evaluation

    Author : Bassel Mannaa; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Newton–Puiseux; Algebraic curve; Sheaf model; Dynamic evaluation; Algebraic number; Grothendieck topos; Grothendieck topos;

    Abstract : Computing the Puiseux expansions of a plane algebraic curve defined by an affine equation over an algebraically closed field is a an important algorithm in algebraic geometry. This is the so-called Newton–Puiseux Theorem. The termination of this algorithm, however, is usually justified by non-constructive means. READ MORE

  5. 5. Ultrasheaves

    Author : Jonas Eliasson; Viggo Stoltenberg-Hansen; Steve Awodey; Carsten Butz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Logic; symbolic and mathematical; 03G30; 03C20; 03H05; Matematisk logik; Mathematical logic; Matematisk logik;

    Abstract : This thesis treats ultrasheaves, sheaves on the category of ultrafilters. In the classical theory of ultrapowers, you start with an ultrafilter and, given a structure, you construct the ultrapower of the structure over the ultrafilter. READ MORE
