  1. 6. Distance Consistent Labellings and the Local List Number

    University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Author : Anders Henricsson; [2023]
    Keywords : distance-consistence; graph labelling; graph distance; avstånds-konsistens; grafmärkning; grafavstånd;

    Abstract : We study the local list number of graphs introduced by Lennerstad and Eriksson. A labelling of a graph on n vertices is a bijection from vertex set to the set {1,…, n}. Given such a labelling c a vertex u is distance consistent if for all vertices v and w |c(u)-c(v)|=|c(u)-c(w)|+1 implies d(u,w)≤ d(u,v). READ MORE

  3. 7. The cosmological polytope of the complete bipartite graph K_{2,n}

    University essay from KTH/Matematik (Avd.)

    Author : Erik Landin; [2023]
    Keywords : Polytopes; Cosmological polytopes; Gröbner bases; Graphs; Polytop; Kosmologiska polytop; Gröbner baser; Grafer;

    Abstract : A cosmological polytope of an undirected connected graph is a lattice polytope which when the graph is interpreted as a feynman diagram can be used to calculate the contribution of that feynman diagram to the wavefunction of some cosmological models. This contribution can be calculated using the canonical form of the cosmological polytope, which can be computed by taking the sum of the canonical forms of the facets of a subdivision of the cosmological polytope.

  4. 8. Coral Reef Restoration Enterprises

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Ileana Graf; [2023]
    Keywords : Coral reef restoration enterprise CRRE ; Nature-based enterprise NBE ; Coral business; Profitable coral reef restoration; Sustainable business model; Business and Economics;

    Abstract : Coral reefs are essential for providing ecosystem services to humans, including coastal protection, nutrition, and income opportunities for coastal communities. However, coral reefs worldwide have suffered severe damage due to anthropogenic factors, leading to their rapid degradation. READ MORE

  5. 9. An experimental analysis of Link Prediction methods over Microservices Knowledge Graphs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gianluca Ruberto; [2023]
    Keywords : Knowledge Graphs; Link Prediction; Machine Learning; Microservice Tracing; Kunskapsdiagram; länkförutsägelse; maskininlärning; mikroservicespårning;

    Abstract : Graphs are a powerful way to represent data. They can be seen as a collection of objects (nodes) and the relationships between them (edges or links). The power of this structure has its intrinsic value in the relationship between data points that can even provide more information than the data properties. READ MORE

  6. 10. Link Prediction Using Learnable Topology Augmentation

    University essay from KTH/Matematik (Avd.)

    Author : Tori Leatherman; [2023]
    Keywords : Network Analysis; Inductive Link Prediction; Learnable Augmentation; Graph Neural Networks; Multilayer Perceptrons; Nätverksanalys; Induktiv Länkförutsägelse; Inlärningsbar Förstärkning; Grafiska Neurala Nätverk; Flerskiktsperceptroner;

    Abstract : Link prediction is a crucial task in many downstream applications of graph machine learning. Graph Neural Networks (GNNs) are a prominent approach for transductive link prediction, where the aim is to predict missing links or connections only within the existing nodes of a given graph.
