  1. 1. Perron-Frobenius' Theory and Applications

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

    Author : Karl Eriksson; [2023]
    Keywords : Positive matrices; nonnegative matrices; Perron-Frobenius; linear dynamical systems; Leslie matrices; Markov chain; Google s PageRank algorithm; Positiva matriser; icke-negativa matriser; Perron-Frobenius; linjära dynamiska system; Leslie matris; Markov-kedja; Google s PageRank algoritm;

    Abstract : This is a literature study, in linear algebra, about positive and nonnegative matrices and their special properties. We say that a matrix or a vector is positive/nonnegative if all of its entries are positive/nonnegative. First, we study some generalities and become acquainted with two types of nonnegative matrices; irreducible and reducible. READ MORE

  3. 2. Perron–Frobenius theorem and Z≥0[S3]-semimodules

    University essay from Uppsala universitet/Algebra, logik och representationsteori

    Author : Mikolaj Cuszynski-Kruk; [2022]
    Keywords : ;

    Abstract : In this thesis, the Perron–Frobenius theorem which in its most general formstates that the spectral radius of a non-negative real square matrix is an eigenvaluewith a non-negative eigenvector, is proven. Related properties arederived, in particular the Collatz–Wielandt formula and a general form of anon-negative idempotent matrices. READ MORE

  4. 3. Managing Expectations : Signalling effects of Federal Reserve Bank announcements over inflation expectations and expected real interest rates

    University essay from Södertörns högskola/Nationalekonomi

    Author : Marianne Hanson; [2022]
    Keywords : monetary policy; communication; signaling; forward guidance; inflation expectations; real interest rates expectations.;

    Abstract : Communication is an important aspect of modern monetary policy. Since the popularization of the inflation targeting framework, communication has been used to manage expectations and maintain credibility. In recent years, forward guidance as a signaling strategy has been recognized as an important tool of monetary policy. READ MORE

  5. 4. Exchange Rates and Trade Flows : An Econometric Analysis of Structural Breaks in the Swedish Trade

    University essay from Uppsala universitet/Nationalekonomiska institutionen

    Author : Lars Winnansson; [2022]
    Keywords : structural breaks; exchange-rates; trade-balance; imports; exports;

    Abstract : This study examines the relationship between the real exchange rate and the trade flows of Sweden in the presence of so-called structural breaks. The purpose is rooted in the hypothesis that the real exchange rate has been disconnected from global trade flows in the aftermath of the Global Financial Crisis (GFC) in 2008. READ MORE

  6. 5. The Uniformization Theorem

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Nikita Zozoulenko; [2021]
    Keywords : complex analysis; riemann surface; analytic functions; holomorphic functions; differential geometry; harmonic; subharmonic; perron; analysis; Mathematics and Statistics;

    Abstract : In this bachelor's thesis we provide a self contained proof of the Uniformization Theorem. It states that a simply connected Riemann surface is conformally equivalent to either the complex plane C, the unit disk D, or the Riemann sphere C^*. READ MORE
