6. Random geometric graphs and their applications in neuronal modelling
Sammanfattning : Random graph theory is an important tool to study different problems arising from real world.In this thesis we study how to model connections between neurons (nodes) and synaptic connections (edges) in the brain using inhomogeneous random distance graph models. LÄS MER
7. Random graph models and their applications
Sammanfattning : This thesis explores different models of random graphs. The first part treats a change from the preferential attachment model where the network incorporates new vertices and attach them preferentially to the previous vertices with a large number of connections. LÄS MER
8. Random Multigraphs : Complexity Measures, Probability Models and Statistical Inference
Sammanfattning : This thesis is concerned with multigraphs and their complexity which is defined and quantified by the distribution of edge multiplicities. Two random multigraph models are considered. The first model is random stub matching (RSM) where the edges are formed by randomly coupling pairs of stubs according to a fixed stub multiplicity sequence. LÄS MER
9. Degrees in Random Graphs and Tournament Limits
Sammanfattning : This thesis consists of an introduction and six papers on the topics of degree distributions in random graphs and tournaments and their limits.The first two papers deal with a dynamic random graph, evolving in time through duplication and deletion of vertices and edges. In Paper I we study the degree densities of this model. LÄS MER
10. Symmetry in Randomness : Additive Functionals and Symmetries of Random Trees and Tree-Like Graphs
Sammanfattning : Properties of symmetries in random trees and tree-like graphs are explored. The primary structures studied are Galton-Watson trees, unlabeled unordered trees as well as labeled subcritical graphs. LÄS MER
