1. 1. To explore and verify in mathematics

   Författare :Tomas Bergqvist; Hans Wallin; Johan Lithner; Morten Blomhøj; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Explorations; mathematical reasoning; empirical investigations; graphing calculators; conjectures.; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK; didactics of mathematics; matematikdidaktik;

   Sammanfattning : This dissertation consists of four articles and a summary. The main focus of the studies is students' explorations in upper secondary school mathematics. In the first study the central research question was to find out if the students could learn something difficult by using the graphing calculator. LÄS MER

3. 2. A tale of trees and leaves : subtrees and local convergence

   Författare :Wang Ruoyu; Stephan Wagner; Haslegrave John; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tree; subtree; mean subtree order; Benjamini Schramm convergence; local convergence; Mathematics; Matematik;

   Sammanfattning : Given a tree T, a subtree in T is a subgraph that is a tree itself. The set of subtrees in a tree is related to many important graph parameters, one of which is the mean subtree order. LÄS MER

4. 3. Alciphron, Letters of the Courtesans : Edited with Introduction, Translation and Commentary

   Författare :Patrik Granholm; Ingela Nilsson; Diether Roderich Reinsch; Heinz-Günther Nesselrath; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Alciphron; letters of the courtesans; Greek letters; fictitious letters; critical edition; parallel translation; commentary; textual notes; textual criticism; manuscript studies; manuscript tradition; Classical Greek language; Klassisk grekiska; Greek; Grekiska;

   Sammanfattning : This dissertation aims at providing a new critical edition of the fictitious Letters of the Courtesans attributed to Alciphron (late 2nd or early 3rd century AD).The first part of the introduction begins with a brief survey of the problematic dating and identification of Alciphron, followed by a general overview of the epistolary genre and the letters of Alciphron.

5. 4. Boolean complexes of involutions and smooth intervals in Coxeter groups

   Författare :Vincent Umutabazi; Axel Hultman; Jan Snellman; Christian Stump; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This dissertation is composed of four papers in algebraic combinatorics related to Coxeter groups. By a Coxeter group, we mean a group W generated by a subset S ⊂ W such that for all s ∈ S , we have s2 = e, and (s, s′)m(s,s′) = (s′ s)m(s,s′) = e, where m(s, s′) = m(s′ s) ≥ 2 for all s ≠ s′ ≥ ∈ S .

7. 5. Tautological Rings of Moduli Spaces of Curves

   Författare :Mehdi Tavakol; Carel Faber; Gavril Farkas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

   Sammanfattning : The purpose of this thesis is to study tautological rings of moduli spaces of curves. The moduli spaces of curves play an important role in algebraic geometry. The study of algebraic cycles on these spaces was started by Mumford. He introduced the notion of tautological classes on moduli spaces of curves. LÄS MER
