  3. 2. On linear graph invariants related to Ramsey and edge numbers : or how I learned to stop worrying and love the alien invasion

    Författare :Oliver Krüger; Jörgen Backelin; Alexander Engström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ramsey number; edge number; minimal Ramsey graph; independence number; clique number; Turán s theorem; crochet pattern; H13-pattern; linear graph invariant; triangle-free graph; Mathematics; matematik;

    Sammanfattning : In this thesis we study the Ramsey numbers, R(l,k), the edge numbers, e(l,k;n) and graphs that are related to these. The edge number e(l,k;n) may be defined as the least natural number m for which all graphs on n vertices and less than m edges either contains a complete subgraph of size l or an independent set of size k.

  4. 3. Asymptotics of Eigenpolynomials of Exactly-Solvable Operators

    Författare :Tanja Bergkvist; Boris Shapiro; Andrei Martinez-Finkelshtein; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exactly-solvable; eigenpolynomials; zero distribution; asymptotics; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : The main topic of this doctoral thesis is asymptotic properties of zeros in polynomial families arising as eigenfunctions to exactly-solvable differential operators. The study was initially inspired by a number of striking results from computer experiments performed by G. Masson and B. Shapiro for a more restrictive class of operators. LÄS MER

  5. 4. Minimal models in algebra, combinatorics and topology

    Författare :Alexander Berglund; Torsten Ekedahl; Alexandru Suciu; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : The thesis consists of seven papers.In Paper I, II, III, IV and V, we study homological invariants of monomial rings — rings of the form R = k[x1, . . . LÄS MER

  7. 5. On Propagation of Boundary Continuity for Domains in Complex Space

    Författare :Salla Franzén; Egmont Porten; Jan-Erik Björk; Ragnar Sigurdsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary behavior of holomorphic functions; Global boundary behavior of holomorphic functions; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : We consider continuity properties of analytic functions in bounded domains in complex space, focusing on the following two questions:Question 1. Given a bounded domain G in complex affine n-space. LÄS MER
