  1. 11. Classification of Financial Transactions using Lightweight Memory Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zhexin Cui; [2022]
    Nyckelord :Fraud Detection; Memory Network; Light-weight Model; Cryptocurrencies; Upptäckt av bedrägerier; minnesnätverk; lättviktsmodell; kryptovalutor;

    Sammanfattning : Various forms of fraud have substantially impacted our lives and caused considerable losses to some people. To reduce these losses, many researchers have devoted themselves to the study of fraud detection. LÄS MER

  4. 13. On a novel soliton equation, its integrability properties, and its physical interpretation

    Master-uppsats, KTH/Fysik

    Författare :Alexander Fagerlund; [2022]
    Nyckelord :Calogero-Moser systems; Conservation laws; Elliptic dynamics; Fluid dynamics; Hamiltonian mechanics; Hyperbolic dynamics; Integrability; Lax pairs; Pole ansatz; Riemann-Hilbert problems; Solitons; Bevarandelagar; Calogero-Mosersystem; Elliptisk dynamik; Fluiddynamik; Hamiltonmekanik; Hyperbolisk dynamik; Integrabilitet; Laxpar; Polansats; Riemann-Hilbertproblem; Solitoner;

    Sammanfattning : In the present work, we introduce a never before studied soliton equation called the intermediate mixed Manakov (IMM) equation. Through a pole ansatz, we prove that the equation has N-soliton solutions with pole parameters governed by the hyperbolic Calogero-Moser system. LÄS MER

  5. 14. Effective quasiparallelogram laws on elliptic curves over number fields

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Douglas Molin; [2021-05-21]
    Nyckelord :height; elliptic curve; quasiparallelogram law; canonical height; difference bounds;

    Sammanfattning : We introduce the classical theory of heights on projective space and prove explicit quasiparallelogram laws for the ordinary height and the naive height on elliptic curves over number fields with shortWeierstrass equations. As corollaries, we obtain bounds for the differences between the classical heights and the canonical height, similar to the well-known Silverman bounds. LÄS MER

  7. 15. Exact eigenstates of the Inozemtsev spin chain

    Master-uppsats, KTH/Fysik

    Författare :Simon Lentz; [2021]
    Nyckelord :Theoretical physics; Mathematical physics; quantum mechanics; many-body problems; spin chain; Inozemtsev; Calogero-Sutherland; Teoretisk fysik; Matematisk fysik; kvantmekanik; mångpartikel problem; spinnkedjor; Inozemtsev; Calogero-Sutherland;

    Sammanfattning : This thesis deals with the following question: are there more eigenfunctions, other than the already known eigenfunctions, of the spin chain with elliptic interactions known as the Inozemtsev spin chain? The Inozemtsev spin chain interpolates between two quantum integrable spin chains, theHeisenberg spin chain and the Haldane-Shastry spin chain. Therefore it is interesting to explore eigenfunctions of the Inozemtsev spin chain in greater detail. LÄS MER
