  1. 1. Perturbed Markov Chains with Damping Component and Information Networks

    Author : Benard Abola; Sergei Silvestrov; Christopher Engström; Dmitrii Silvestrov; Anatoliy Malyarenko; Milica Rancic; Vladimir Anisimov; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : This thesis brings together three thematic topics, PageRank of evolving tree graphs, stopping criteria for ranks and perturbed Markov chains with damping component. The commonality in these topics is their focus on ranking problems in information networks. READ MORE

  2. 2. Analytical and Iterative Methods of Computing PageRank of Networks

    Author : Pitos Seleka Biganda; Sergei Silvestrov; Christopher Engström; Dmitrii Silvestrov; Anatoliy Malyarenko; Milica Rancic; Oleg Seleznjev; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : This thesis is about variants of PageRank, methods of PageRank computation and perturbation analysis of a PageRank vector as a stationary distribution of a kind of perturbed Markov chain model. Chapter 2 of this thesis gives closed form formulae for ordinary and lazy PageRanks for some specific simple line graphs.

  3. 3. Kähler-Poisson Algebras

    Author : Ahmed Al-Shujary; Joakim Arnlind; Milagros Izquierdo; Sergei Silvestrov; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : In this thesis, we introduce Kähler-Poisson algebras and study their basic properties. The motivation comes from differential geometry, where one can show that the Riemannian geometry of an almost Kähler manifold can be formulated in terms of the Poisson algebra of smooth functions on the manifold.

  4. 4. PageRank in Evolving Networks and Applications of Graphs in Natural Language Processing and Biology

    Author : Christopher Engström; Sergei Silvestrov; Raimondo Manca; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : This thesis is dedicated to the use of graph based methods applied to ranking problems on the Web-graph and applications in natural language processing and biology.Chapter 2-4 of this thesis is about PageRank and its use in the ranking of home pages on the Internet for use in search engines.

  5. 5. Extreme points of the Vandermonde determinant and phenomenological modelling with power exponential functions

    Author : Karl Lundengård; Sergei Silvestrov; Milica Rancic; Anatoliy Malyarenko; Palle Jorgensen; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : This thesis discusses two topics, finding the extreme points of the Vandermonde determinant on various surfaces and phenomenological modelling using power-exponential functions. The relation between these two problems is that they are both related to methods for curve-fitting. READ MORE
