  1. 1. The Elliptic Curve Method : A Modern Approach to Integer Factorization

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Felix Cao; [2023]
    Nyckelord :Pollard s p-1 method; Factorization; Elliptic curves; Lentra s; Elliptic curve method;

    Sammanfattning : In this paper, we present a study of elliptic curves, focusing on theirunderlying mathematical concepts, properties and applications in numbertheory. We begin by introducing elliptic curves and their unique features,discussing their algebraic structure, and exploring their group law, pro-viding examples and geometric interpretations. LÄS MER

  3. 2. Hamlade träds värde: trädets roll inom olika miljöer

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Viktor Dahlbom; [2021-06-21]
    Nyckelord :Pollarding; biologiskt kulturarv; landscape; value; management;

    Sammanfattning : The question about value is an ever going subject. This paper aims to conduct a case study on selected environments that has to do with pollard trees and compare different approaces regarding these trees and their value. Previous research has shown that the value differs from biological and cultural. LÄS MER

  4. 3. Comparison of mortality rate forecasting using the Second Order Lee–Carter method with different mortality models

    Master-uppsats, Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Författare :Hisham Sulemana; [2019]
    Nyckelord :Mortality rate; Power-exponential function based model; Modified Perks model; Heligman and Pollard HP4 model; Model fitting; Forecasting; Central death rate; Second order Lee–Carter method; Mortality indices; Comparison.;

    Sammanfattning : Mortality information is very important for national planning and health of a country. Mortality rate forecasting is a basic contribution for the projection of financial improvement of pension plans, well-being and social strategy planning. LÄS MER

  5. 4. Klassgruppen Introduktion, faktorisering och implementation

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Isak Ohlsson Ångnell; [2019]
    Nyckelord :;

    Sammanfattning : Givet ett heltal n så utforskar denna text olika sätt att hitta ns faktorer, med fokus på Shanks Klassgruppmetod, även om korta beskrivningar av Pollards p -1- och rho-algoritmer ges. Klassgruppen introduceras som en mängd av ekvivalensklasser av fraktionsideal i imaginära kvadratiska talkroppar, varpå en isomorfi till en mängd av ekvivalensklasser av binära kvadratiska former av given diskriminant D ges.

  7. 5. Pollard's rho method

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Ida Bucic; [2019]
    Nyckelord :Number theory; Factorization; Floyd s cycle finding algorithm;

    Sammanfattning : In this work we are going to investigate a factorization method that was invented by John Pollard. It makes possible to factorize medium large integers into a product of prime numbers. We will run a C++ program and test how do different parameters affect the results. LÄS MER
