1. 1. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Daniel Nilsson; Magnus Bertilsson; [2022]
   Keywords : QFT; Quantum; Quantum field theory; scattering amplitudes; Berends Giele Currents; feynman diagrams; n particle scattering;

   Abstract : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

3. 2. eulerr: Area-Proportional Euler Diagrams with Ellipses

   University essay from Lunds universitet/Statistiska institutionen

   Author : Johan Larsson; [2018]
   Keywords : Euler diagrams; Venn diagrams; ellipses; R; computer graphics; area-proportional; software; Mathematics and Statistics;

   Abstract : Euler diagrams are common and intuitive visualizations for data involving sets and relationships thereof. Compared to Venn diagrams, Euler diagrams do not require all set relationships to be present and may therefore be area-proportional also with subset or disjoint relationships in the input. READ MORE

4. 3. Investigation of SomeCognitive Difficulties inSet Theory

   University essay from Institutionen för matematikämnets och naturvetenskapsämnenas didaktik

   Author : Razmjooei Ayaz; [2013]
   Keywords : College students; Euler–Venn diagrams; inclusion and belonging; cognitive difficulties; semiotic activities; set theory;

   Abstract : A previous study on students approach to problems of Set Theory in Iran brought me somehypotheses. These encouraged me to test the hypotheses in this supplementary study. Mypurpose of this study was to consider some students' cognitive difficulties in Set Theory. READ MORE
