  1. 1. Stokes' Theorem: Integration of Differential Forms Over Chains

    University essay from KTH/Fysik

    Author : Joel Wållberg; [2022]
    Keywords : Stokes theorem; Differential forms;

    Abstract : The aim of this work is to introduce differential forms on Euclidean space. The theory of differential forms provides a way of abstracting integration by formalising differentials over which an integral can be taken. The work builds towards Stokes’ Theorem for which a proof is given. READ MORE

  3. 2. Higher Forms and Dimensional Hierarchy in Topological Condensed Matter

    University essay from KTH/Fysik

    Author : Yashar Honarmandi; [2022]
    Keywords : Theoretical physics; topological quantum matter; parametrized systems; Berry phase; higher Berry curvature; effective field theory; topological action; topological insulators; dimensional hierarchy; Teoretisk fysik; topologisk kvantmateria; parametriserade system; Berryfas; högre Berrykrökning; effektiv fältteori; topologisk verkan; topologiska isolatorer; dimensionshierarki;

    Abstract : This report discusses higher differential forms with applications in the study of topological phenomena. The integer quantum Hall effect is first discussed, demonstrating a connection between models on a lattice and quantum field theories bridged by a topological invariant, namely the Chern number.

  4. 3. Energy poverty and the elderly-care: Exploring energy poverty in the elderly-care through case studies with social welfare organizations in Taiwan

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Tzu Ling Kuo; [2020]
    Keywords : Science General;

    Abstract : The topic of energy poverty has recently gained prominence amongst researchers and academia in Taiwan within the context of rising energy prices and low emission energy transitions. Social welfare organizations (SWOs) that provide 24-hour residence and care for vulnerable populations, such as the elderly and disabled, highly depend on various energy services and are likely to be significantly affected due to rising energy prices, adding to their existing financial pressure.

  5. 4. Comparative Analysis of Adaptive Domain Decomposition Algorithms for a Time-Spectral Method

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

    Author : Vilhelm Dinevik; [2020]
    Keywords : ;

    Abstract : Time-spectral solvers for partial differential equations (PDE) have been explored in various forms during the last few decades. The generalized weighted residual method (GWRM) is one such method with a high accuracy and efficiency. The GWRM has so far been implemented almost exclusively with a uniform grid of subdomains in the spatial domain. READ MORE

  6. 5. The Impact of Financial Advisors on Risk Arbitrage Spreads: Evidence from Nordic Takeover Bids

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Gustav Berg; Erik Johansson; [2020]
    Keywords : Financial Advisors; Mergers and Acquisitions; Risk Arbitrage; Arbitrage Spreads;

    Abstract : Following the announcement of a public takeover bid, the target firm's stock price generally adjusts towards the offer price. However, these rarely converge, and the percentage difference that emerges forms what is commonly referred to as the risk arbitrage spread. READ MORE
